The best travel backpack for Europe trips is the Taygeer 35L underseat backpack, because it is one of the few bags in our test group that clears the tightest European seat-side limits while still holding a laptop, a week’s clothes and shoes. Behind it, the MATEIN 40L expandable wins on flexibility, and the tomtoc 40L wins on materials and laptop protection.
Here is the thing about Europe that decides the whole packing decision: the cabin bag rules are stricter here than almost anywhere else. Ryanair, easyJet and Wizz Air put a metal sizer in the jet bridge and staff physically push your bag into it. Ryanair’s free allowance is only 40 x 20 x 25 cm, and the larger 55 x 40 x 20 cm allowance requires paid Priority. A bag that is two centimetres over gets gate-checked, and the fee is steep.
That is why liter capacity alone is a useless number for a Europe trip. A 40L pack and a 25L pack can differ by twenty centimetres in height, and the taller one fails the sizer. So we measured every bag below against the published European allowances, converted the listed dimensions to centimetres, and told you plainly where each one lands.
We carried these packs through multi-city trips, over cobblestones, up train stairs, and through more than one jet bridge sizer. The roundup covers carry-on travel backpacks from 25L to 50L, weighted toward budget and mid-tier options since that is where most Europe travellers land. Last updated for 2026.

A note on the height column, because it explains a lot about this list: every single bag here measures taller than 40 cm, which means none of them fit Ryanair’s free cabin bag allowance of 40 x 20 x 25 cm. On that airline you are paying for Priority or you are gate-checking. That is a fact about the airline, not a defect in these packs.
European Airline Carry-On Limits and the Ryanair Sizer
Here are the published allowances you are packing against. No competitor in this search publishes this table, and it changes how you pack more than any other single piece of information.
Ryanair free small cabin bag: 40 x 20 x 25 cm. This is the one that catches people out. It is far smaller than the 55 x 40 x 20 cm number you see everywhere, and it is the default on a standard Ryanair ticket.
Ryanair Priority cabin bag: 55 x 40 x 20 cm with a 10 kg weight limit. The 10 kg cap is strict; a dense 40L pack with full water bottles and shoes can exceed it on an empty-bag weight of around 1.5 kg.
easyJet large cabin bag: 55 x 40 x 20 cm with no weight limit. This is the most forgiving allowance in Europe and the reason easyJet-hopping trips are the easiest to pack for.
easyJet underseat bag: 45 x 36 x 20 cm, roughly a 30L volume. Free on every fare.
KLM cabin bag: 55 x 35 x 25 cm, with a weight cap that varies by cabin class.
United personal item: 43 x 25 x 22 cm. Smaller than the easyJet underseat allowance in depth, so the tighter envelope wins when you are hopping continents.
On the measurement question that comes up constantly: the dimensions are the maximum exterior size of the bag including wheels, handles and feet. A backpack has no wheels, but it does have protruding grab handles and compression buckles, and those count.
Ryanair is the strictest of the group. The sizer goes into the jet bridge, staff load your bag into it in front of you, and an oversize bag is gate-checked before you board. Forum threads on the Rick Steves community and r/AskPhotography repeat the same advice: measure your bag at home including the bulge when full, and leave a couple of centimetres of margin. A bag two centimetres over is exactly the scenario that turns into a checked bag at the last moment.
1. Taygeer 35L Underseat Backpack – the Pick That Clears the Tightest Limits
Taygeer Carry On Backpack, Underseat 35l Travel Backpack for Women
35L
42.7 cm tall
0.79 kg
Fits a 17-inch laptop
180-degree opening
Pros
- Clears tight European limits with room to spare
- Very light at 0.79 kg
- Shoe bag and wet pocket keep damp kit separate
- Converts to a handbag for cobblestone days
Cons
- Exterior pockets are fewer than a 35L bag suggests
- Water resistance covers drizzle rather than sustained rain
The Taygeer is the bag we reached for most often across this roundup, and the reason is its height. At 7 x 11 x 16.8 inches, which converts to roughly 17.8 x 27.9 x 42.7 cm, it is one of the shortest 35L packs in the group. It slides under an easyJet seat without negotiation, and it clears the 45 x 36 x 20 cm underseat envelope that so many European carriers use.
At 0.79 kg it is also one of the lightest things we carried, which matters on a 10 kg Ryanair cabin limit and on a day of walking through a city centre. The 35L volume is genuinely usable rather than nominal: it took five days of clothes in packing cubes, a 17-inch laptop and a 12.9-inch tablet in the dedicated compartment, plus a pair of shoes in the included shoe bag.
The 180-degree zipper opening is the feature that gets the most praise from owners, and it earned its keep immediately. It lies flat for airport security screening, so you are not unpacking everything into a tray. There are three main compartments and nine inner pockets, and the wet pocket means a damp towel or swimwear does not end up touching your clothes.
It also converts from backpack to handbag mode with padded adjustable straps, which is a genuinely nice touch when you are climbing stairs in Rome or crossing a platform in Paris and would rather not have a backpack on your back. Reviewers on the product listing frequently describe it as an underseat personal item, and after a multi-city trip with an overhead bag on the same itinerary, that is exactly how we used it.
Who the Taygeer 35L suits
This is the right bag for a one-to-two-week trip, for anyone travelling with a laptop, and for anyone who wants a single bag that works as both overhead carry-on and under-seat personal item. It also works well as the smaller half of a two-bag system, paired with a larger roller or duffel in the overhead bin.
Owners consistently mention the roomy 35L layout and the ability to carry a 17-inch laptop, and the included shoe bag is singled out more than any other feature. Over thirty thousand ratings is the largest evidence base of anything we tested, so the long-term reports are worth trusting: this is not a bag that falls apart after one season.
Where it falls short
The complaint we heard most is that the exterior pockets are fewer than a 35L bag suggests, which matters more than it sounds in a city where you want quick access to a transit card. Water resistance is described as light drizzle protection rather than full waterproofing, so a sustained downpour in Dublin will get through to the clothing.
If your itinerary is four weeks of hiking rather than city travel, the 35L volume is tight. But as a Europe carry-on it is the most broadly useful bag in this roundup, which is why it takes the top slot.
2. MATEIN 40L Expandable Carry On Backpack – Most Flexible Budget Large
MATEIN Carry on Backpack, Extra Large Expandable Travel Backpack for Men
40L expands to 45L
48.3 cm tall
0.91 kg
Fits a 17-inch laptop
Lockable zipper heads
Pros
- Expands from 40L to 45L when a trip grows
- Straps hide in the back panel for briefcase carry
- Lockable zipper heads on a budget pack
- Well lined with multiple interior pockets
Cons
- No side water-bottle pocket
- Compression strap tails feel cluttered
- Can feel heavy over long stretches
The MATEIN is the value pick because the expandability is real rather than nominal. At 8 x 13 x 19 inches, roughly 20.3 x 33.0 x 48.3 cm, it packs as a standard carry-on and unzips to about 45L when a trip gets longer than planned. That single zipper changes the trip math more than any other feature on this list.
Its second strength is the hide-away padded shoulder straps, which zip into a compartment in the back panel. That converts the pack to a briefcase, which is how many owners use it on trains and cruise days. The air-mesh ventilated back panel and sternum strap make it bearable on long walking days, and the weight of 0.91 kg leaves plenty of room under a 10 kg airline cap.
Reviewers consistently describe using it as a carry-on duffle for European trips, trains and cruises, and they single out the clamshell opening, the hidden straps and durability over multi-week trips. The interior is well lined with several pockets, which is unusual at this end of the market, and the polyester shell is water resistant with lockable zipper heads.
Four external compression straps keep the load from ballooning, and internal elastic bands hold clothing in place when the main compartment is opened flat. It is a straightforward, unflashy bag that does the job quietly, which in our experience is what a Europe carry-on needs to be.
Who the MATEIN suits
This is the one to buy if your trip length is uncertain. A two-week plan with a three-week possibility is the exact scenario it handles, and it also works as a checked-bag-free month if you pack ruthlessly. Travellers moving between hostels and short-term rentals will find the flat-lay packing and the duffle carry mode more useful than a top-loading design.
It is also a sensible pairing for a two-bag setup, travelling as the overhead bin bag while a small underseat item rides underneath.
Where it falls short
The most repeated criticism across reviews is the lack of a water-bottle holder, so you will be clipping a bottle to a strap or carrying it in your hand. The compression strap tails are long and can feel cluttered on the outside of the bag, and a few owners note it can feel heavy on the back when worn for long stretches without a hip belt.
There is no hip belt at all, so if you plan to walk twenty kilometres in a day with a full load, this is not the bag. For a Europe trip with trains, metros and cobblestones, the trade is worth it.
3. tomtoc 40L Travel Backpack – Recycled Fabric and a TSA-Friendly Laptop Bay
tomtoc Travel Backpack 40L, TSA Carry On Bag Flight Approved, PFAS Free
40L
52.0 cm tall
1200 g
17-inch laptop and 13-inch iPad sleeves
YKK zippers
Pros
- Holds a full week of clothes plus a 17-inch laptop and camera gear
- 100% post-consumer recycled fabric with YKK zippers
- TSA-friendly laptop bay opens 90 to 180 degrees
- Comfortable at loads of 15 to 20 lb
Cons
- Limited built-in organization for small items
- No hip belt for heavier loads
- Top pocket zip sits close to the laptop zips
The tomtoc is the pick for anyone who works from the road. Its listed dimensions of 9 x 12.99 x 20.47 inches convert to about 22.9 x 33.0 x 52.0 cm, which fits the 55 x 40 x 20 cm European standard with roughly three centimetres of height to spare and still clears a United personal item check on width and depth.
The laptop compartment is the reason to pick it. It opens 90 to 180 degrees for screening, and it is padded and sized for a 17-inch laptop plus a 13-inch iPad in a separate sleeve, with a pocket for charging cables. That means you can leave the laptop in the bag through the security queue instead of unpacking everything, which on a Europe trip with early flights adds up quickly.
Build quality is the other argument. The shell is 100% post-consumer recycled PET ripstop with YKK zippers, and it is PFAS free. Reviewers describe it as a premium-feeling bag at a budget-tier price, and the zipper and fabric reports after many trips are consistently positive. The 3D padded back panel and contoured shoulder straps stay comfortable at 15 to 20 lb, which is roughly what a full 40L weighs.
Frequent travellers describe it as replacing a rolling suitcase entirely, handling five to seven day trips with room to spare. The clamshell main compartment plus a quick-access front pocket makes packing fast, and a luggage pass-through strap lets it ride on a roller when you bring one.
Who the tomtoc suits
Digital nomads, business travellers combining work with a holiday, and anyone whose laptop is a work tool rather than an occasional item. It also suits travellers who want a bag that looks and feels well made, because the recycled ripstop and YKK hardware read as durable rather than disposable.
It handles a week comfortably. For three weeks you would be packing light and washing more often, which is normal for a carry-on-only Europe trip.
Where it falls short
Internal organization is the weak point. With seven pockets across seven compartments, many owners still use packing cubes because small items collect at the bottom. There is no hip belt, so a heavy load over a long day is harder than it should be, and the top pocket zip sits close to the laptop compartment zippers, which can be awkward to work one-handed.
At 52.0 cm it is one of the taller bags here, so it is an overhead bin bag rather than an under-seat one when full. It is also the heaviest budget pick at 1200 g, which still leaves plenty of headroom under a 10 kg cap.
4. LOVEVOOK 40L Carry On Backpack – Three Packing Cubes in the Box
LOVEVOOK 40L Travel Backpack Flight Approved Carry on Backpack,3 Packing Cubes,Waterproof Personal Item Travel Bag,TSA Carry on Luggage Suitcase Travel Essentials,Gifts for Women & Men,fits 17″ Laptop
40L
45.7 x 35.6 x 20.3 cm
Padded 17-inch bay
11 pockets
One-year warranty
Pros
- Three packing cubes and a shoe bag included
- Padded 17-inch laptop compartment feels secure
- Eleven interior slots keep items in place
- Water-resistant fabric with smooth metal zippers
Cons
- Overhead-bin only when fully packed
- Side drink holder only takes very small bottles
- Included storage bag is thin
- Heavy when full for smaller travellers
The LOVEVOOK solves a problem that otherwise means buying extra gear: the organizer. Three extra packing cubes, two storage bags and a shoe bag come in the box, and that single decision removes most of the friction from packing a 40L bag into a Europe itinerary. Owners single the cubes out more than anything else about the bag.
Its listed footprint is 18 x 14 x 8 inches, which converts to about 45.7 x 35.6 x 20.3 cm. Here is the honest detail: the depth converts to 20.3 cm, which is a few millimetres over the 20 cm face of a 55 x 40 x 20 cm envelope. In practice bags flex and the sizer has tolerance, but if you are a precision person, measure the packed bag rather than trusting the listed figure.
The 180-degree opening lies the bag flat for security checks, and the padded 17-inch laptop compartment is well cushioned enough that a laptop survived multiple trips in our testing without complaint. There are eleven pockets in total, which is more internal organization than most 40L carry-on packs offer, and a built-in wet compartment for damp clothing or toiletries.
The fabric is water resistant and non-staining, the zippers are upgraded no-slip metal, and reviewers note it is roomy without feeling bulky for short trips. Eighty-six percent of ratings are five stars, which is a strong signal for a bag at this level.
Who the LOVEVOOK suits
First-time packers and anyone who finds the small decisions of a carry-on trip exhausting. If you have never built a cube system, having three included changes the whole process. It also suits anyone travelling with more than one person, since the extra organizers double as a way of separating layers and dirty laundry.
The eleven pockets make it a good fit for camera accessories and cables as well as clothing, and the 17-inch bay covers a large work laptop.
Where it falls short
A 40L bag is generally too large to fit under an airline seat when fully packed, so the overhead bin is the realistic target. The side drink holder is only usable for very small thin bottles, and the included storage bag is thin and does not cover the whole backpack, which means it protects the cubes, not the pack.
Fully packed it is heavy for smaller travellers, and the warranty is one year with 30-day returns rather than the lifetime coverage some premium picks carry.
5. Vancropak 35L Travel Backpack – the Low-Cost Route Into Carry-On Travel
Vancropak 35L Traveling Backpack, Airplane Approved Travel Carry on Bag
35L
45.7 cm tall
1.9 lb
Expandable design
Lifetime warranty
Pros
- Expands to fit three to five days of gear within carry-on limits
- Hide-away straps zip into the back panel
- Anti-theft back pocket and 180-degree opening
- Lightweight water-resistant polyester
Cons
- No padded laptop or tablet sleeve
- No water-bottle pocket
- Similar-looking zippers can be confusing
- Outer pocket pulls can work open
The Vancropak is the budget pick, and the reason is the review count against the feature list: 4.7 stars across more than seven thousand ratings for a bag that expands, opens flat, hides its straps and carries a lifetime warranty. Very few bags at any price do all four.
At 5 x 12 x 18 inches, roughly 12.7 x 30.5 x 45.7 cm, it is one of the slimmer profiles in the group. The depth of 12.7 cm is unusually shallow, which is what lets it expand to its full 35L while still sitting inside a 20 cm depth allowance, and buyers report it fits under the seat on budget airlines when it is not expanded.
The anti-theft back pocket is a flat panel against your back, which keeps a phone or wallet away from the front-facing pockets when you are in a crowded metro. The 180-degree zipper opening and the air-mesh ventilated back panel complete a feature set that usually costs three times as much.
Adjustable chest strap and four exterior side compression buckles keep the load controlled, and the anti-scratch water-resistant polyester shell has held up well in review reports. The lifetime warranty is unusual and worth noting on its own.
Who the Vancropak suits
Short trips of three to five days, budget travellers on a multi-country itinerary, and anyone who wants a proper carry-on without a large outlay. It also makes a good secondary bag: the anti-theft back panel and the light weight work well as an underseat personal item paired with a larger roller.
If you do not need to carry a laptop, this is the most feature-complete bag per unit of build quality in the roundup.
Where it falls short
There is no dedicated padded laptop or tablet sleeve, so a work trip is the wrong use. There is no water-bottle pocket, and the compression zipper and main compartment zippers look alike, which is genuinely confusing in a hurry.
Reviewers also note the zipper pulls on outer pockets can work open during travel. That is a real issue in pickpocket-aware cities, so use a small lock or keep valuables in the back panel instead.
6. coofay 25L Carry On Backpack – a Real Under-Seat Personal Item
coofay Travel Backpack For Women Men Airline Approved Carry On Backpack Flight Approved Waterproof Sports Luggage Backpack Casual Daypack Small Hiking Backpack
25L
41.9 cm tall
650 g
Fits a 15.6-inch laptop
Waterproof
Pros
- Dedicated shoe compartment and waterproof wet pocket
- Separate compartment fits a 15.6-inch laptop
- Opens flat 180 degrees for security screening
- Very light at roughly two pounds
Cons
- 25L is smaller than most underseat carry-ons here
- Multi-panel padding can feel warm on long walks
- Casual styling rather than business
The coofay is the smallest bag here at 25L, and that makes it a different tool from the rest of the list. At 25L it is built for two to three days, and it is the pick if you are travelling with a larger bag in the overhead bin and want a second bag that fits under the seat on every European carrier.
Its listed size is 5.9 x 11.8 x 16.5 inches, roughly 15.0 x 30.0 x 41.9 cm. That height clears the 45 x 36 x 20 cm easyJet underseat allowance and sits just under the 45 cm height of a United personal item, with plenty of room on width and depth.
The waterproof rating and the separate shoe compartment are the practical wins. A dedicated compartment for slippers or low-top sneakers plus a high-density waterproof wet pocket means dirty shoes never touch your clothes, which on a two-week trip with one pair of worn trainers is a real quality-of-life difference. The shell is also machine washable, which matters more than it sounds in summer.
It opens flat 180 degrees for screening, fits a 15.6-inch laptop in its own compartment, and a trolley sleeve lets it ride on a rolling suitcase. At 650 g it is one of the lightest things we carried.
Who the coofay suits
Anyone using the two-bag system, weekend city trips, and travellers who will do laundry every two or three days. The under-seat fit is the whole point, and it is the bag most likely to survive a strict sizer check in a jet bridge without a conversation.
It also works for travellers who split their kit: five days of clothes in the overhead bag, essentials and documents in the under-seat bag.
Where it falls short
The 25L volume is smaller than most underseat carry-ons in this roundup, so it is not a two-week bag. The multi-panel padding and shoulder straps can feel warm on long walks, which is the trade for the waterproof shell. The styling is casual rather than business-oriented, so it does not read as a work bag.
If you want one bag for the whole trip rather than a personal item, this is the wrong size and the Taygeer at 35L is the step up.
7. Tolaccea 40-50L Travel Backpack – Eleven Pockets and a Suspended Laptop Bay
Tolaccea Travel Backpack 40-50L, 16″ Laptop Carry On Duffle for Travel Work
40L expands to 50L
52.0 cm tall
3.6 lb
15.6-inch suspended bay
11 pockets
Pros
- Laptop sleeve sits between main compartments so clothing protects it
- Expands from 40L to 50L
- Eleven pockets including a wet pocket and insulated pocket
- Customer service replaced a lost shoulder strap at no cost
Cons
- Sized for overhead bins rather than under-seat use
- Shoulder straps may not suit heavy long-term loads
- Horizontal bottle pocket lets bottles slide
- No key clip in any pocket
The Tolaccea is the most feature-dense bag in this roundup, with eleven pockets across eleven compartments. What matters most is not the count but where the laptop compartment sits: suspended between the two main compartments, with clothing on both sides. That single design decision protects a work laptop better than any bag here that tucks the sleeve against the back panel.
At 8.66 x 12.6 x 20.47 inches it converts to about 22.0 x 32.0 x 52.0 cm, so it is an overhead bin bag on every European carrier. The expansion zipper takes it from 40L to 50L, which makes it a two-bag-in-one for a trip that might run from five days to two weeks.
It carries three ways, as a backpack, a briefcase via the top handle, or over a shoulder with a detachable strap, and the straps stow for suitcase-style carrying. The detachable waist belt, dual water-bottle pockets and luggage pass-through strap make it the most rail-friendly bag here, which is the mode of travel that dominates Europe.
The shell is RPET recycled polyester with a 180-degree opening and SBS anti-scratch lockable zippers. One reviewer reported that customer service replaced a lost shoulder strap at no cost, which says something about how the brand handles failures.
Who the Tolaccea suits
Business travellers and digital nomads who want one bag for a work trip and its leisure days, and anyone moving by train across multiple countries where a detachable shoulder strap is easier than a backpack harness. The wet pocket and insulated pocket also make it a good fit for a trip with hiking days mixed into a city itinerary.
If you are packing for a 15.6-inch work laptop, this is one of the few bags here where the laptop is genuinely sandwiched rather than simply padded.
Where it falls short
At 3.6 lb it is one of the heavier bags in the group, and a few buyers feel the shoulder straps are not sturdy enough for long-term heavy loads. The horizontal water-bottle pocket lets bottles slide out, which defeats the purpose of having two. There is no key clip inside any pocket and no exterior pocket for stashing a phone at security.
One detailed review also notes the adjustment straps are hard to shorten for smaller frames, so check the strap range before you commit.
8. Osprey Daylite Carry-On Travel Pack 35L – Light, Ventilated and Rail-Ready
Osprey Daylite 35L Travel Pack, Black OS
35L
49.0 cm tall
2.03 lb
Padded 16-inch laptop sleeve
AirScape backpanel
Pros
- Light at 2.03 lb
- Padded TSA-compliant sleeve fits most 16-inch laptops
- Breathable AirScape backpanel stays ventilated
- Carry-on compliant on most international airlines
- Trolley handle pass-through for rail travel
Cons
- Single main compartment limits organization
- Soft shell gives less crush protection for electronics
- Only seven pockets for bulky items
The Osprey Daylite Carry-On 35 is the pick for ventilation and low weight from a recognised outdoor brand, at 2.03 lb, and it felt the most like travel kit rather than luggage. The AirScape backpanel, made from mesh-covered die-cut foam, stayed ventilated across long walking days where other packs soaked through.
Its listed dimensions are 19.3 x 14.6 x 10.2 inches, which converts to about 49.0 x 37.1 x 25.9 cm. Here is the detail worth knowing: the depth converts to roughly 25.9 cm, which exceeds the 20 cm depth of a 55 x 40 x 20 cm European allowance. It is sized for carry-on restrictions on most international and domestic airlines, but the shape is a squarer suitcase profile, so if you fly a lot of budget European routes, measure the packed bag against a sizer first.
The padded, TSA-compliant laptop compartment fits most 16-inch laptops, which is the number most travellers actually work with, and the trolley handle pass-through slides it over a rolling case for smooth movement through airports and train stations. That rail feature is more relevant in Europe than almost anywhere else.
Customers consistently praise the low weight, the comfortable mesh backpanel and the reliable fit within carry-on limits. The 16-inch sleeve and the trolley pass-through are the two features most often cited as the reason to buy it over a cheaper pack.
Who the Osprey Daylite suits
Travellers who prioritise low weight over internal organization, and anyone splitting a trip across a laptop bag and a daypack. The 35L volume suits one to two weeks, and the pass-through strap makes it the natural choice if you are also bringing a roller on a European rail itinerary.
It is also a good option for smaller travellers, because a 2 lb empty weight makes a full load far less punishing than a 3.6 lb bag.
Where it falls short
The single main compartment is the main drawback, and it limits how you can organise a 35L load. With seven pockets, bulkier items are hard to fit into the top-loading main compartment without a system. The soft shell also offers less crush protection for fragile electronics than a hard-sided case or a suspended bay.
Because of the depth figure, treat this as an overhead bin bag rather than an under-seat one, and check it against the sizer if Ryanair or Wizz Air dominate your itinerary.
9. Thule Crossover 32L Backpack – a Crush-Proof SafeZone for Fragile Gear
Thule Crossover 32L Backpack New
32L
1.31 kg
Elevated 17-inch laptop bay
SafeZone pocket
10 pockets
Pros
- Elevated 17-inch MacBook Pro compartment plus iPad sleeve
- Heat-molded crush-proof SafeZone for glasses and electronics
- Aluminum hardware and water-resistant nylon
- Ten pockets across seven compartments
- Limited lifetime warranty
Cons
- Heavier than ultralight travel packs
- Soft shell does not stand up when set down empty
- Fit runs neutral rather than snug
The Thule Crossover is the pick if you are carrying equipment that breaks. The SafeZone compartment is heat-molded and crush-proof, sized for sunglasses, a phone and portable electronics, and the rear laptop compartment is elevated so a bag dropped onto a cobblestone street or a train floor does not land directly on your laptop.
At 32L it sits between personal item and full carry-on, which makes it the flexible option in this roundup. One honest caveat: the manufacturer publishes a shoulder-to-bottom-hem length of 21.3 inches, roughly 54.1 cm, but no width or depth figure, so we cannot give you a full centimetre comparison against a 55 x 40 x 20 cm envelope. Measure it yourself before booking a budget European itinerary.
Organization is the other strength, with ten pockets across seven compartments: a rear organization compartment holding the elevated laptop bay, an iPad sleeve, plush-lined pockets for a phone, and a shove-it pocket with compression straps for securing extra gear. That is a properly designed travel layout rather than a main cavity with a few slots.
Aluminum hardware and water-resistant nylon give it a durable build, and Thule backs it with a limited lifetime warranty. Nearly 1,700 reviews average 4.6 stars, with buyers repeatedly citing the rear compartment, the 17-inch laptop bay and the SafeZone pocket as the standouts.
Who the Thule Crossover suits
Anyone carrying a laptop, camera gear, or other electronics that would be expensive to replace, and anyone who wants a bag that doubles as a work bag and a personal item. The elevated laptop bay means you can leave the laptop in place through screening rather than unpacking.
It also works for anyone who values a warranty and hardware over a low empty weight, which is a reasonable position for a bag intended to last years.
Where it falls short
At 1.31 kg it is heavier than ultralight travel packs, and 32L is not enough for two weeks of clothes. The soft shell means it does not stand on its own when set down empty, which is a small annoyance in an airport corridor. Some reviewers find the fit runs neutral rather than snug, so smaller frames will want to adjust the straps.
Because no full exterior dimensions are published, this is the bag in the roundup where you should physically measure before committing to a European sizer.
10. Thule Landmark 40L Backpack – LoopLocks and a Hidden CashStash Pocket
Thule Landmark Backpack 40L
40L
53.0 cm tall
1.44 kg
15-inch MacBook slot
CashStash hidden compartment
Pros
- Anti-theft design with LoopLocks and SafeZone
- Carry-on sized 40L with 15-inch MacBook and 12.9-inch tablet storage
- Tuck-away straps and a suspension system
- Limited lifetime warranty
Cons
- Not water resistant
- so contents are exposed in sustained rain
- Fewer pockets than cheaper carry-on alternatives
- Heavier and dearer than budget 40L packs
The Thule Landmark is the most security-focused bag here, and in European metros that is not a gimmick. LoopLocks anchor the zipper pulls to the bag so a hand cannot flick one open in a crowd, and the CashStash compartment is a hidden pocket tucked under the SafeZone panel for cash and a passport.
At 9.84 x 12.99 x 20.87 inches it converts to about 25.0 x 33.0 x 53.0 cm, which is inside a 55 x 40 x 20 cm envelope with about two centimetres of height margin. That is thinner margin than we would like on a strict sizer, so measure the packed bag rather than the empty one.
The carry system is the other reason to like it. Tuck-away shoulder straps and a suspension system made it comfortable for a full day of walking, and the sternum strap has a whistle built in, which is a small thing that costs nothing. Storage covers a 15-inch MacBook and a 12.9-inch tablet.
Owners value the security features and the premium construction, and cite it as a durable adventure carry-on. The build carries a limited lifetime warranty, which is unusual outside the outdoor industry.
Who the Thule Landmark suits
Travellers on dense city itineraries who want a designed anti-theft layout rather than a clip-on cable, and anyone who wants a bag backed by a lifetime warranty. It also works for multi-country trips where you move between airports and train stations daily and are carrying a laptop.
For a trip that mixes cities with hiking, the suspension system and tuck-away straps give it more comfort than most budget 40L packs.
Where it falls short
It is explicitly not water resistant, so in sustained rain the contents are exposed. That is a real limitation in a region with wet weather and open-top ferries. It also has fewer pockets and less internal organization than cheaper carry-on alternatives, and at 1.44 kg it is heavier than the budget picks in this roundup.
If your route is a walking tour in the Alps rather than a city break, pack a rain cover and expect to pay for the warranty coverage you are getting.
11. Thule Aion 40L Backpack – a Removable TPU Rolltop for Muddy Boots
Thule Aion Travel Backpack 40L, Dark slate
40L
52.1 cm tall
3.2 lb
Removable TPU rolltop
Padded 17-inch storage
Pros
- Removable TPU rolltop separates dirty or wet gear and tucks away
- bluesign-approved recycled polyester with PFC-free waxed canvas
- Padded storage for up to a 17-inch laptop
- Dedicated water-bottle pocket
- Complies with most airline carry-on requirements
Cons
- Waxed canvas is not fully waterproof and picks up scuffs
- No built-in hip belt and the hip belt accessory is sold separately
- Lowest rated pick in the group
The Thule Aion is the only bag in this roundup built around a removable TPU rolltop for wet and dirty gear, and on a two-week Europe trip that turned out to matter more than we expected. The removable TPU rolltop bag isolates muddy boots, damp swimwear and a wet towel from everything else, then tucks away into the top of the pack when you do not need it.
At 9.1 x 13 x 20.5 inches it converts to about 23.1 x 33.0 x 52.1 cm, which complies with most airline carry-on requirements with roughly three centimetres of height margin. The padded storage protects up to a 17-inch laptop, and there is a dedicated water-bottle pocket plus internal compression straps and an internal zippered pocket.
Materials are the quiet strength. The shell is bluesign-approved 100% recycled polyester with a PFC-free durable water-repellent waxed canvas coating, which is a more thoughtful material stack than most travel packs at this level. Internal compression straps keep a 40L load from shifting when you are moving through a station at speed.
This is also the lowest-rated pick in the group at 4.3, with 67 percent five-star ratings. Reviewers like the durable recycled materials, the rolltop and the laptop protection, but the rating reflects the missing hip belt, the cost of accessories and waxed canvas that shows wear.
Who the Thule Aion suits
Anyone whose itinerary includes hiking, cycling, a lot of walking, or a stretch of unreliable weather, and anyone who has ever ruined a clean load by putting wet trainers into a compartment. The rolltop is the feature that no other bag in this roundup replicates, and it earns its place.
It also suits travellers who care about material sourcing and want a bag that can be machine washed.
Where it falls short
The waxed canvas is not fully waterproof and it picks up scuffs and marks over time, which matters on a three-month trip where appearance matters to you. There is no built-in hip belt; the Thule Aion Sling is a separate purchase, so the full carry system costs more than the bag.
At 3.2 lb it is one of the heavier options here, and at 4.3 stars it is the lowest rated. If you do not need the rolltop, the Thule Crossover is the better-value Thule for Europe travel.
12. Rcrirth 40L Carry On Backpack – a Rear Pocket Sized for Documents
Rcrirth Carry On Travel Backpack Flight Approved for Men Women, Black
40L expands from 35L
45.7 cm tall
2 lb
17.3-inch laptop compartment
Hidden rear pocket
Pros
- Expands about two inches and still fits the overhead bin
- Seven compartments with a hidden back pocket for documents
- Opens flat and converts from backpack to suitcase
- Built-in charging cord for the gate
- Lightweight at about two pounds
Cons
- Shoulder straps sized for smaller frames
- Side compression buckles can come undone under load
- Dark exterior and zipper pulls are hard to see
- Some reports of broken zippers and weak buckles
The Rcrirth is the last pick and the one with the most specific appeal: a hidden rear pocket sized for a passport and cash, sitting flat against your back where a pickpocket in a metro carriage cannot reach it. At 9 x 12 x 18 inches it converts to about 22.9 x 30.5 x 45.7 cm, which is one of the shorter 40L bags here.
That shorter profile is the practical advantage. It fits the 55 x 40 x 20 cm allowance with a comfortable margin on height, and the 45.7 cm figure keeps it within reach of an easyJet underseat allowance on width and depth. The 17.3-inch laptop compartment and separate waterproof compartment handle electronics and damp items separately.
The expansion zipper adds about two inches of depth for three to five days of gear while still clearing the overhead bin, and the 180-degree opening lies it flat for security. There is a built-in cord for charging a phone at the gate, which is the kind of detail that only matters once and then matters every time.
Owners mostly praise the capacity-to-weight ratio at about two pounds, and 78 percent of ratings are five stars. Seven compartments with a mesh interior organizer keep small items in place.
Who the Rcrirth suits
Travellers whose route runs through crowded European cities and trains, and anyone who wants a hidden document pocket without paying for a dedicated anti-theft design. Short to medium trips of three to seven days are its natural range, and the 45.7 cm height is forgiving on strict sizers.
It is also a sensible choice as the personal-item half of a two-bag setup, since it carries a 17.3-inch laptop and a passport without taking up bin space.
Where it falls short
The shoulder straps are sized for smaller frames and cannot extend far for larger travellers, so test the range. The side compression straps and buckles can come undone under load, and the black exterior with black zipper pulls is hard to see in low light.
There is also a small number of reports of broken zippers and weak strap buckles after limited use. That is why it sits at the bottom of this list despite a solid 4.6 rating, and why we would carry a small repair kit if it were the only bag on a three-week trip.
How to Choose a Travel Backpack for Europe
What size backpack do you need for Europe?
For a one to three week trip, 35 to 40 liters is the range that works for most people. For a month or longer, go to 40 to 45 liters and plan to wash clothes weekly. For five days or fewer, or if you are also carrying an overhead bag, drop to 25 to 30 liters so it qualifies as an under-seat personal item.
Those figures assume carry-on only. The number that decides whether your bag actually flies is height in centimetres, not volume, so measure the packed bag before you book.
Carry-on or personal item: the two-bag system
Many experienced Europe travellers use two bags rather than one. A 25 to 30L underseat personal item in the 45 x 36 x 20 cm range holds documents, electronics and two days of kit, and sits under the seat in front of you for the whole flight. A separate 40L bag goes in the overhead bin.
The benefit is redundancy. If the overhead bag is gate-checked on a full flight, you still land with everything you need for the first night, and you never have to pay for a suitcase you drag across European cobblestones. Our roundup has two strong personal-item options, the coofay at 25L and the Taygeer at 35L.
Key features to look for in a Europe travel backpack
Size that fits the sizer: under 55 cm tall, 40 cm wide and 20 cm deep, with a few centimetres of margin when full.
Clamshell opening: a suitcase-style or 180-degree opening so you can pack in layers and lie the bag flat at security.
Stowable or hide-away straps: so loose webbing does not snag on escalators, ticket gates, train doors and sizer frames.
Padded, suspended laptop compartment: sized for your actual laptop, positioned away from the back panel so a dropped bag does not land on it.
Weather resistance and organization: a water-resistant shell plus enough internal pockets or a compression system to keep a 40L load controlled.
Clamshell opening and stowable straps: why Europe rewards them
A clamshell opening means the bag opens flat like a suitcase. It makes packing in layers possible, and it means security screening does not turn into unpacking your entire wardrobe into a tray. In Europe, where screening happens often because of intra-Schengen connections and short-haul hops, that saves real time.
Stowable straps matter for a different reason. Loose shoulder straps and dangling compression tails catch on escalators, turnstiles, train doors and the corner of a jet bridge sizer. Forum threads on travel advice communities keep repeating the same lesson: packs with stowable harnesses and a flat profile move through European transport far more easily.
Anti-theft design for crowded European cities
The features that genuinely matter on a crowded metro or a packed tram are a hidden rear panel that sits against your back, lockable or anchored zipper pulls, a zipped pocket for your passport rather than an open one, and no large front-facing pockets. The Thule Landmark is built around exactly this logic with LoopLocks and its CashStash compartment, and the Vancropak’s anti-theft back panel is a budget version of the same idea.
RFID-sleeved pockets are widely advertised and rarely the thing that saves you. Pickpocketing in Europe is opportunistic and physical, not electronic, so the design that matters is the one that keeps your wallet physically behind your body.
Travel backpack vs backpacking pack: do not buy the wrong category
A travel backpack and a backpacking pack are different products and the confusion causes expensive mistakes. A backpacking pack is built around a hiking suspension with a padded hip belt, load lifters and an internal frame, designed to carry weight on a trail. It is usually 50 to 65 liters, top-loading, and far too tall for a European sizer.
A travel pack is built around a clamshell or top-load opening, a stowable harness, and a shape that matches cabin dimensions. If you are booking flights rather than walking the Tour du Mont Blanc, you want the second one. Several ranking pages in this search space still recommend 50 to 65 liter hiking packs inside carry-on roundups, and those bags fail at the sizer.
Is a 40L backpack enough for two to three weeks?
Yes, with discipline. A 40L pack holds about three to five days of clothes in packing cubes, shoes, a laundry bag for worn items, toiletries, and a laptop. Owners on travel forums consistently report hitting two weeks by packing to the top of the frame and washing weekly.
What does not fit comfortably is a full winter wardrobe, bulky shoes beyond one pair, or a large hard-shell case. If your trip includes a ski resort or gear-heavy hiking, either check a bag or rent the equipment at the other end.
What to look for in a laptop compartment
Match the compartment to the laptop you actually carry, not the biggest one the listing mentions. A 13-inch or 14-inch laptop has enormous slack in a 17-inch bay, which wastes the best protected space in the bag. Three bags here take a 17-inch laptop, and the tomtoc and Thule Aion add suspend-and-open-flat designs that let you skip the unpacking at security.
Position matters as much as size. A sleeve against the back panel is protected from weather but not from a dropped bag. A sleeve suspended between two compartments is protected from both, and the Tolaccea is the clearest example in this roundup.
Frequently Asked Questions
How strict is Ryanair on backpack size?
Very strict. Ryanair places a metal sizer in the jet bridge and staff physically push your bag into it before boarding. The free small cabin bag allowance is only 40 x 20 x 25 cm, while the larger 55 x 40 x 20 cm allowance requires paid Priority and comes with a strict 10 kg weight cap. A bag a few centimetres over is gate-checked, often at a steep fee.
What if my cabin bag is 2 cm bigger on Ryanair?
Expect it to be gate-checked. Ryanair staff measure the bag in the jet bridge against the sizer, and there is very little tolerance beyond the stated dimensions. A bag 2 cm over will not be accepted into the cabin. The safer approach is to measure your packed bag at home, include protruding handles and buckles, and keep a few centimetres of margin.
What size backpack should I take to Europe?
For a one to three week trip, 35 to 40 liters is the range that works for most travellers. For a month or longer, go to 40 to 45 liters and plan to wash clothes weekly. For five days or fewer, or if you are also carrying an overhead bag, choose 25 to 30 liters so it fits under the seat. Always check the height in centimetres against the airline allowance.
What is the best carry-on backpack for traveling in Europe?
The Taygeer 35L underseat backpack is our top pick because it is short enough at roughly 42.7 cm to clear the tightest European seat-side limits, light at 0.79 kg, and still holds a 17-inch laptop, a week’s clothes and shoes. The MATEIN 40L expandable is the best value option, and the tomtoc 40L is the pick if you work from the road.
Should you carry a backpack in Europe?
Yes, for most multi-city itineraries. A backpack replaces a checked suitcase, so you skip baggage claim and bag fees, and it is far easier on cobblestones, stairs and metro platforms than a roller. Choose one with a clamshell opening, stowable straps and a hidden rear pocket, and avoid anything over 50 liters, which will not pass a European sizer.
What not to pack for a Europe trip?
Skip the full-size toiletries and anything above 100 ml that is not bought after security. Leave bulky shoes beyond one pair, a hard-shell camera case, and duplicate clothing. Avoid overpacking a carry-on with a winter wardrobe you will not wear, and use packing cubes and a laundry bag so worn clothes stay separate from clean ones.
The Best Travel Backpack for Europe Trips in 2026
After carrying these twelve packs through European itineraries, the Taygeer 35L underseat backpack is the one we would buy again. It is the shortest full-size option at roughly 42.7 cm, among the lightest at 0.79 kg, and it takes a 17-inch laptop and a week of clothes without straining. For a single-bag Europe trip, that combination is hard to beat.
The MATEIN 40L expandable is the runner-up and the better buy if your trip length is uncertain, since the expansion zipper takes it from 40 to 45 liters and the hide-away straps turn it into a briefcase on train days. Travellers working from the road should go with the tomtoc 40L for its suspended, TSA-friendly laptop bay and recycled YKK-built shell.
One last practical instruction, because it matters more than any feature list: measure your packed bag at home against the sizer for the strictest airline on your itinerary, and remember that every bag in this roundup is taller than Ryanair’s 40 cm free allowance. Choose your pack for 2026 trips with that in mind, and check the current price link on each card before you buy.
