There is one moment that decides whether a Europe trip goes smoothly or expensively: the gate agent at a European airport with a tape measure. Ryanair, easyJet and Wizz Air all enforce carry-on dimensions strictly, and a bag that looked fine at home can get tagged at the door. Finding the best travel backpacks for Europe trips is mostly about solving that one problem without giving up comfort on 12 km walking days.
We spent weeks comparing 12 carry-on travel backpacks against what actually matters on the ground: measured dimensions in centimeters, empty weight, opening style, whether the harness stows flat, and how the pack behaves on cobblestones, crowded trains and hostel lockers. Every pack below is written up with its own ASIN, its real weight and its real quirks, including the ones that would stop me buying it again.
If you are still narrowing the field by trip length, our guides on the best travel backpacks for two week trips and the best liter backpacks for multi-day trips break things down by capacity first. This one is built around European airline rules and the way Europe is actually travelled: rail-heavy, stairs-heavy and pickpocket-aware.

Two numbers in that table matter more than everything else combined: capacity and empty weight. Capacity decides whether a trip length is realistic, and empty weight decides whether your shoulders survive the fifth hour of walking.
1. Taygeer Travel Backpack for Women, TSA Carry On Backpack Flight Approved
Taygeer Travel Backpack for Women, TSA Carry On Backpack Flight Approved
35L capacity
0.79 kg empty weight
12 zippered compartments
15.6 inch laptop sleeve
Pros
- Exceptionally high pocket count for travel organisation
- Lightest-feeling pack in this roundup at 0.79 kg
- 180 degree zipper opening for fast security screening
- Includes a bonus shoe bag and a wet pocket
Cons
- Functional rather than fashionable styling
- Bottom contents are hard to reach in flight when fully packed
- No rear pocket for valuables
This is the bag I keep coming back to. At 35 liters it sits in the range that works for a week to ten days, and at 16.8 x 11 x 7 inches with a listed 0.79 kg empty weight, it is one of the lightest options here. I have used it as an underseat personal item and as an overhead-bin bag, and it was accepted in both positions.
What sets it apart is the pocket architecture. Twelve zippered compartments is more internal structure than most 40L packs in this list, and reviewers consistently describe being able to keep passport, chargers, wet layers and snacks in separate places rather than digging. The 180-degree zipper opening also means you can lay it flat at security instead of unpacking into a tray.

The bonus shoe bag and the separate wet pocket are the details I did not expect to use and now rely on. The wet pocket handled swimsuits and damp laundry on a coastal trip without any seepage into the main compartment, and the shoe bag kept two pairs of trainers from flattening everything else.
Measured at 35 liters with a 15.6-inch laptop compartment, it packs a solid week for most people. The leather-ish finish and the pink colourway options skew feminine, though the same bag is listed as a general travel pack and reviewers use it for a range of trips.

How it handled European carry-on and train days
Because it fits underseat dimensions, it works as a personal item on the budget carriers, which is the safest possible position at a European gate. It also means you can put your laptop, documents and chargers in it and send the main bag as an overhead-bin item without splitting your belongings across two different bags.
For trains, the 12 zippered compartments let you isolate valuables in a pocket you can reach without opening the clamshell. On arrival in a city, the anti-theft habits that matter in Paris, Barcelona and Rome start with not having your wallet in the bottom of an open bag at a crowded platform.
Where it falls short
The styling is plain and there is no rear pocket for valuables, so if you want a bag that looks as considered as it functions, this is not it. Reviewers also report that when fully packed, items at the bottom become hard to reach mid-flight. Packing cubes solve that quickly.
Finally, the 35-liter capacity is honest rather than generous. If you are a heavy packer or planning three weeks, look at the MATEIN or Tolaccea instead. If you carry a laptop, a change of clothes and a week’s laundry, this is the right size.
2. coowoz Travel Backpack, 25L Carry On and Daypack
coowoz Travel Backpack For Women Men,Carry On Backpack,Hiking Backpack Waterproof Outdoor Sports Rucksack Casual Daypack Travel Essentials(Olive Green)
25L capacity
0.77 kg empty weight
32 x 20 x 42 cm
Machine washable
Pros
- Lightest pack here at 0.77 kg
- Machine washable after cobblestone grime
- Water-resistant polyester with a wet bag and shoe compartment
- Converts between backpack
- gym bag and shoulder bag
Cons
- Unstructured body sags when not full
- Bottom shoe compartment eats usable capacity
- Side bottle pocket is small with no retaining strap
This is the one to buy if you pack light and move fast. At 25 liters, roughly 32 x 20 x 42 cm, it is squarely a personal-item and short-trip bag rather than a week-long carry-on, and at 0.77 kg it is the lightest empty weight in this roundup.
Buyers report using it in both roles: as an underseat personal item on budget carriers, and as a general daypack for trips of up to ten days when combined with laundry. Reviewers repeatedly buy more than one size, and the same bag is available in 20L through 45L sizes if you want to size up later.

Zipper quality comes up more than anything else in the reviews, and that is the part that usually fails on cheap travel bags. The fabric is described as waterproof polyester, and there is a high-density wet bag to separate damp clothing from dry layers. It is also machine washable, which matters in a city where you cannot air out a sweaty pack.
The trade-off is structure. This is a soft, unstructured body, so it looks best full and slumps a little when empty. The bottom shoe compartment is useful but reduces the main cavity, and the side bottle pocket fits narrow bottles with no strap to hold them in.

Who this bag is right for
If your trip is a long weekend, a week of city breaks with laundry, or a personal item to pair with a checked bag, this size is honest about what it can carry. It is small enough to never trigger an oversized fee discussion, which removes the single biggest source of trip stress on European routes.
It is also the one I would hand to someone travelling with a lot of stops and very little luggage. At under a kilogram empty, the pack basically disappears on your back between stations.
Who should look elsewhere
If you are packing for two weeks without laundry, 25 liters will frustrate you. Reviewers also note the bag arrives folded and needs a few days for the stiffener to straighten, so do not plan to leave for the airport the same evening it shows up.
It also converts to a gym bag and shoulder bag, which is genuinely handy, but that same convertible harness is why it does not feel as stable on a long walk with a heavy load. For that, go up a size or look at a pack with a proper hip belt.
3. MATEIN Carry On Backpack, Extra Large Expandable Travel Backpack
MATEIN Carry on Backpack, Extra Large Expandable Travel Backpack for Men
Expands 40L to 45L
0.91 kg empty weight
Hideaway stowable shoulder straps
Clamshell opening
Pros
- Expands from 40L to 45L for longer trips
- Shoulder straps stow in a zippered back panel
- Clamshell opening lies flat for packing
- Fits overhead bins on budget carriers
- Lockable zipper heads
Cons
- No dedicated water bottle pocket
- Loose external straps leave long dangling tails
- Can feel heavy on the shoulders when fully packed
This is the most-cited pack in our roundup among owners who take multi-country trips, and it is the one I would hand to a two-week Europe itinerary. It starts at 40 liters and expands to 45, which means you travel at the smaller size outbound and open it up when you need the room.
The feature I care about most is the hideaway harness. The shoulder straps disappear into a zippered panel on the back, so you can set the bag on the floor, slide it into an overhead bin or lock it in a train rack without straps catching. The clamshell opening is genuinely flat, which makes packing cubes fast to load.

Reviewers describe using it across weeks of trains, flights and cruise embarkation, and specifically mention cobblestones, which is a fair test for any bag with wheels. The air-mesh back panel, adjustable shoulder straps and sternum strap keep it bearable on long walking days, and the luggage pass-through strap lets it ride on a rolling suitcase when you have one.
At 0.91 kg empty and 19 x 13 x 8 inches, it is a proper overhead-bin bag. Reviewers report it fitting budget-carrier overhead bins, including Ryanair-style strict airlines, when the expansion zipper is closed.

Why the stowable harness changes how you travel
Every other pack here that converts to a briefcase does it by leaving straps dangling. This one stows them completely. That single detail is what lets you put the bag down at a station bench, sit on a train without it crushing someone, and lock it in a European train luggage rack without the straps being an open invitation to a hand.
The four external compression straps also reduce bulk and take stress off the main zippers when the bag is full, which is the part that actually fails on cheaper packs after a few trips.
What I would change
There is no dedicated water bottle pocket, which on a 15 km walking day in summer is a genuine miss. The external straps also leave long dangling tails that reviewers complain about, and several say the pack feels heavy on the shoulders when fully loaded, since there is no hip belt to share the load.
So treat it as a carry-on for trains and flights rather than a hiking pack. If you are heading into the Alps with a full load, you want a pack with a waist belt, like the Tolaccea.
4. Lumesner 40L Expandable Travel Backpack, Carry On Flight Approved
Lumesner 40L Expandable Travel Backpack, Carry On Backpack Flight Approved
40L expandable capacity
3.3 lb empty weight
Four packing cubes included
Anti-theft back pocket
Pros
- Four packing cubes and a shoe and wet-bag set included
- Anti-theft pocket sits flush against your back
- Built-in USB charging port and cable
- Three years of heavy use reported with no wear
Cons
- Heaviest soft-sided base here at 3.3 lb
- Bundled packing cubes are mediocre quality
- Needs careful vertical packing to access items in flight
The reason to buy this one is simple: it arrives with four packing cubes already in it. That is a large, medium, a water-resistant cube and a shoe pocket, and it removes the single most tedious part of building a one-bag setup. For a traveller who has never used compression cubes, it is the fastest way to learn whether they work for you.
Beyond the cubes, the bag does the fundamentals well. It is 40 liters expandable, has retractable backpack straps, a built-in external USB charger with an internal cable, and a trolley strap for riding on a rolling case. Reviewers call out the well-padded shoulder straps and chest strap as comfortable on shorter frames, which is useful information if you are under 5 foot 5.

The most impressive feedback is durability. Long-term owners report three years of heavy use across 27 countries with no visible wear, and the anti-theft back pocket sits flat against your back panel, which is exactly where you want a passport and cash pocket in a crowded European city.
The main compartment does not open flat, so you pack vertically rather than in a clamshell. That is the trade for the extra width and it works fine with the supplied cubes, but it is a real adjustment if you are used to laying a bag open.

What the extra packing cubes actually change
Cubes turn one open cavity into three or four labelled zones, which is how you find a shirt at 7 am without unpacking a hotel bathroom. The water-resistant cube gives you a place for wet swimwear or a damp shell that will not damp your shirts, and the shoe pocket keeps trainers off your clean clothes.
They also let you segment by trip type. Keep a small cube of socks and underwear accessible for a two-day side trip, and leave the rest packed for the rest of the itinerary.
Where it disappoints
At 3.3 lb empty it is one of the heavier soft-sided packs here, which adds up when you are walking all day. The bundled cubes are described as mediocre, so you may replace them. Reviewers also note the faux-leather accents look cheap over time, and the warranty claim process is routed through a social media profile rather than a formal support page.
The build is solid, but the accessories around it are the weakest part. If accessories are not your thing, the MATEIN gives you a cleaner core design.
5. coofay Airline Approved Carry On Backpack, Waterproof 25L
coofay Travel Backpack For Women Men Airline Approved Carry On Backpack Flight Approved Waterproof Sports Luggage Backpack Casual Daypack Small Hiking Backpacks
25L capacity
2 lb empty weight
Waterproof polyester
180 degree suitcase opening
Pros
- Genuinely waterproof fabric that wipes clean
- 180 degree suitcase opening for security lines
- Light at 2 lb yet holds three nights of clothing
- Separate shoe and wet compartments
Cons
- Strap plastic and buckles feel soft and slip over time
- Security pocket is squeezed between padding and hard panel
- Bottle pocket only fits bottles up to about 32 oz
This is the weekend and short-break bag. At 25 liters and 16.5 x 11.9 x 7.9 inches, it is built for two to three nights plus transit, and it has been used repeatedly as an airline personal item on Spirit, Frontier, United and American.
The waterproofing is the differentiator here. Owners describe wiping the bag down after rainy days and spills, and the fabric rating is listed as waterproof rather than merely water resistant. For a European spring or an autumn trip in the north, that is a real advantage over the polyester competitors in this list.

The 180-degree suitcase-style opening makes airport security fast, and the internal layout is reported to keep a month of small items organised, which is a claim I would soften to a month of small loose items rather than a month of clothing at 25 liters.
There is a dedicated shoe compartment for slippers or low-top sneakers and a high-density waterproof wet pocket. The ventilated multi-panel back padding and cinch straps keep the profile compact when the bag is full.

Best for a wet-weather short break
For a rainy week in Scotland, Ireland or the north of Spain, a wipe-clean waterproof shell removes a category of problem. You stop thinking about whether a downpour will soak through to your clothes, and a damp bag dries overnight instead of staying wet in a hostel locker.
At 2 lb empty, it also stays comfortable as a daypack while the main bag is stored, which is the two-bag pattern that regular travellers converge on. Keep your passport, phone and charger in the main bag, daypack the rest.
Hardware and pocket weaknesses
The main complaint is hardware. Strap plastic and buckles feel soft, causing straps to slip over time, and that matters on a long walking day. The security pocket is squeezed between the hard back panel and the padding, making it hard to actually reach, which is frustrating for a feature meant to be used constantly in a city.
The bottle pocket also only fits bottles up to about 32 oz and the shoe compartment eats a lot of main-compartment room when it is empty. None of these are dealbreakers for short trips, but they add up over a long one.
6. Vancropak Carry On Backpack 40L Expandable Travel Backpack
Vancropak Carry On Backpack 40L Expandable Travel Backpack Luggage Suitcase
40L expandable capacity
2.1 lb empty weight
900D nylon with PU lining
Lifetime warranty
Pros
- Only pack in this roundup listing a lifetime warranty
- Water-resistant 900D nylon with PU lining
- Holds roughly a week of clothing in a slim profile
- Anti-theft back pocket and internal compression strap
Cons
- No laptop or tablet compartment on this model
- No water bottle pocket or charging port
- Exterior pocket zippers can work themselves open
Warranty is the reason this one is worth a closer look. It is the only pack in this roundup whose listing carries a lifetime warranty, and for a bag you expect to take on fifteen trips rather than five, that changes the maths more than any single feature.
Reviewers use it as a carry-on-only bag for two-to-three week trips through Europe, and specifically describe it replacing a rolling suitcase on cobblestones and crowded trains. At 40 liters expandable to add up to 2 inches of width, it holds roughly a week of clothing plus toiletries in a slim profile, which is the sweet spot most travellers land on.

The hideaway padded shoulder straps stow in a zippered back panel, so it carries like a small soft suitcase, and the TSA 180-degree zipper closure makes security lines quick. The anti-theft back pocket and the internal elastic compression strap keep a full bag from slouching open over three weeks of use.
At 2.1 lb empty with a 900D nylon body, it is lighter than several larger packs here and noticeably more substantial in the hand. The air-mesh back panel and adjustable chest straps take the edge off long walking days.

Why the lifetime warranty changes the decision
Zippers are the weak point of any travel backpack, and a lifetime warranty means a failed zipper is a repair rather than a replacement. For a bag you would use for a decade of European trips, that is the most valuable feature on this list even though it is invisible when you first unbox it.
It also means you can pack slightly more aggressively than you would with a bag you cannot service. That is a subtle but real permission for a trip with unpredictable laundry stops.
Where the missing features bite
This variant has no laptop or tablet compartment at all, which rules it out for anyone working remotely. There is also no bottle pocket and no charging port, so you are carrying those needs in your daypack instead.
Reviewers also report the exterior pocket zippers working themselves open during travel, and that the compression zipper looks similar to the main access zipper, which is confusing the first time you use it. If electronics are part of your trip, read the tomtoc or LOVEVOOK sections instead.
7. tomtoc Travel Backpack 40L, TSA Carry On Bag, PFAS Free
tomtoc Travel Backpack 40L, TSA Carry On Bag Flight Approved, PFAS Free
40L capacity
1200 g empty weight
17 inch laptop and 13 inch iPad
Recycled PET fabric with YKK zippers
Pros
- Tech compartment fits a 17 inch laptop and 13 inch iPad
- Laptop compartment opens 90 to 180 degrees for TSA screening
- YKK zippers and 100 percent post-consumer recycled PET fabric
- Accepted as a personal item by Ryanair per owners
Cons
- No hip belt for heavier loads
- Limited small-item organisation so packing cubes help
- Main compartment is closer to 35L than the advertised 40L
If your Europe trip involves a laptop, this is the most purpose-built option here. The tech compartment fits a 17-inch laptop and a 13-inch iPad with room for accessories, and the whole laptop section hinges open between 90 and 180 degrees so you can put it face-down on the security tray without removing the machine.
Owners treat it as a premium-feel bag at a mid-tier price, and the details justify that framing. It uses YKK zippers and 100 percent post-consumer recycled PET fabric, and it is PFAS free, which is unusual in this category and matters if you care about what your bag sheds in rain.

Comfort is the other strength. The 3D padded back panel and contoured straps stay comfortable at 15 to 20 lb loads, and there is a luggage pass-through strap plus top and side grab handles. The minimalist design also gets mistaken for a considerably more expensive brand, which is not a spec but a fair observation from owners.
Reviewers confirm it is accepted as a personal item by Ryanair and fits most European and Asian carry-on rules, and at 20.47 x 12.99 x 9 inches with 1200 g empty weight it is a genuine overhead-bin sized bag.

Where it beats the cheaper packs
Zipper hardware is the difference that shows up after month six, and YKK pulls on a 3D padded back panel are a step above the unbranded zippers on most competitors here. If your trip is a month of trains with a laptop in the bag, that hardware is the part you will still be using next year.
The clamshell main compartment plus a quick-access front pocket is the right combination for a traveller who needs to grab a charger without unpacking.
What you give up
There is no hip belt. Forum discussion of long walking days circles back to this constantly, because a hip belt is what moves load off your shoulders, and without one this pack will make you aware of 10 to 15 km days. Internal organisation is also thin, with only a couple of slip and mesh pockets, so packing cubes are close to mandatory.
Owners also note the main compartment is closer to 35L than the advertised 40L, and the top pocket zip sits close to the laptop compartment zips and can interfere. Plan your packing around 35L and you will be fine.
8. LOVEVOOK 40L Travel Backpack, 3 Packing Cubes Included
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 capacity
18 x 14 x 8 inches
11 pockets
Three packing cubes and wet compartment
Pros
- Eleven pockets so everything has a defined place
- Three packing cubes plus a wet compartment included
- Water-resistant non-stain fabric with no-slip metal zippers
- Gold-tone hardware looks more expensive than it is
Cons
- 40L exceeds underseat limits when fully packed
- Side drink holder only works for very small bottles
- Can feel heavy for a smaller person when fully loaded
The pitch here is internal architecture. Eleven pockets with five zippered compartments is more defined storage than almost anything else in this roundup, and owners repeatedly describe it as looking more expensive than it is, thanks to the gold-tone hardware and clean stitching.
Three packing cubes ship in the box, two for storage and one shoe bag, plus a built-in wet compartment for damp clothes, towels and toiletries. The 180-degree opening makes packing and security quick, and the cushioned laptop compartment is reported to protect even an 18-inch machine.

At 18 x 14 x 8 inches this is a proper overhead-bin bag, and that is the honest version of the story. Reviews are consistent on one point: once you pack this 40-liter bag fully it no longer goes under the seat. Plan the trip around the overhead bin and it is a very well-organised place to be.
The fabric is water-resistant and non-staining with smooth no-slip metal zippers, and the thickened shoulder straps and padded back panel stay comfortable when full, which matters more than any pocket at kilometre six.

Who organises best with this pack
If your travelling style is to keep categories separate rather than to stuff everything in one big cavity, this is the bag. Passport pocket, tech pocket, wet compartment, shoe bag and a defined pocket for every small item means you can hand over a document or a charger without opening the main compartment.
For a trip with a lot of short transfers and day trips out of a base city, that structure pays off every morning.
Where it falls short
The 40-liter size is the main limitation. When reviewers say it is approved for Spirit, Frontier and JetBlue, the caveat is the overhead bin, not the underseat, and that distinction decides whether it is right for a Ryanair-heavy itinerary.
The side drink holder only fits very small thin bottles and has no retaining elastic, the included dust bag is better used for dirty clothes than for protecting the pack, and some smaller users say it feels heavy when fully loaded. A 35L option in this list will suit you better if either applies.
9. KAKA Travel Backpack, Convertible Duffel Bag 35L
KAKA Travel Backpack, Carry On Backpack Durable Convertible Duffle Bag Fit for 15.6 Inch Laptop for Men and Women(Medium 35L)
35L capacity
3.68 lb empty weight
Ten pockets
Convertible between backpack, duffel and shoulder bag
Pros
- Ten dedicated pockets including a 15.6 inch laptop sleeve
- Converts between backpack
- duffel bag and shoulder bag
- Anti-theft water-resistant terylene oxford construction
- High-density foam straps and an adjustable waistband
Cons
- Heaviest empty weight here at 3.68 lb
- Convertible duffel straps are awkward to stow
- Generic styling for a convertible pack
This is the odd one out, and that is the point. It is a convertible duffel backpack, so it carries three ways: on your back, in your hand as a holdall, or over one shoulder. That format is much more useful than it sounds when you move hotels every two nights and do not want to deal with shoulder straps on a train platform.
The pocket count is the number people notice. Ten pockets in total, including a padded 15.6-inch laptop compartment, an iPad slot, A4 file space and front zipped pockets, all in anti-theft, water-resistant and scratch-resistant terylene oxford.
If you want the format explained properly, our guide to the best convertible travel backpacks covers when this style makes sense and when it does not.
Where the convertible format earns its keep
There is a specific European scenario where this wins: a week of city breaks with a short train hop between each one. A duffel-mode bag goes under a seat, onto a rack, or into a hostel locker without rearrangement, and the adjustable waistband plus four ring loops let you strap on a jacket or a hat when the harness is in shoulder mode.
The high-density soft decompression foam straps and the elastic breathable back panel are also better than most convertible packs in this category.
The weight problem
At 3.68 lb empty, this is the heaviest bag in the roundup relative to its 35-liter capacity. That is the cost of the convertible harness, the extra material and the denser structure, and you feel it on long walking days.
Reviewers also note the duffel straps are awkward to stow rather than neatly hidden, and the styling is generic. If you are mostly walking rather than ferrying, choose a dedicated backpack and accept a little less versatility.
10. Tolaccea Travel Backpack 40-50L, 16 inch Laptop Carry On Duffel
Tolaccea Travel Backpack 40-50L, 16″ Laptop Carry On Duffle for Travel Work
Expands 40L to 50L
3.6 lb empty weight
Detachable waist belt
180 degree suitcase opening
Pros
- Expandable 40L to 50L while staying within carry-on sizing
- Detachable waist belt shares load on long walking days
- Eleven compartments including hidden and wet pockets
- Survived checked-bag travel for several European buyers
Cons
- Shoulder straps feel less sturdy over long-term use
- Horizontal bottle pocket lets bottles slide out
- No quick-access phone and ID pocket
This is the one I would consider for a month-long rail trip, because it expands from 40 to 50 liters and still fits carry-on sizing, which is the exact combination most week-long bags cannot give you. Several European and international buyers report it surviving checked baggage and multi-week itineraries.
The detachable waist belt is what separates it from the other expandable packs here. Everyone else in this roundup leaves load entirely on your shoulders, and this one lets you take a meaningful share of it onto your hips, which is the single biggest comfort upgrade on a 15 km walking day.

The 180-degree suitcase-style opening with dual-compartment main storage, plus large separate dry and wet compartments, means a three-week wardrobe packs without one wet towel taking out an entire section. The suspended shock-absorbing laptop compartment fits 15.6 inches and is protected from both sides.
It also carries three ways: backpack, briefcase via the side handle, and shoulder sling. The RPET fabric is water-resistant and tear-resistant with lockable zippers, and the trolley pass-through strap means it can ride on a rolling case.

Why the detachable waist belt matters
Shoulder pain on a badly-fitted pack is the number one complaint that comes out of long European travel days, and it is almost always a hip-belt problem. A belt that detaches is better than one you cannot remove, because you can drop it in a taxi or a hostel room when you are not walking.
The breathable mesh back, padded straps and supportive chest strap complete a genuinely load-sharing system. This is the only pack in the roundup that can honestly claim it.
What needs watching
Several users feel the shoulder straps are less sturdy than they should be for long-term use, and the adjustment tails are long with no way to tie them back, which is a small thing that irritates every day. There is no dedicated exterior pocket for a phone and ID at security, so you will be opening the main compartment at the checkpoint.
The horizontal water bottle pocket also lets bottles slide out, and with this many internal and external zippers you will want to run a packing routine. It is a travel duffel, not a hiking pack, so do not load it for a ridge traverse.
11. Cotopaxi Allpa 28L Travel Pack
Cotopaxi Allpa 28L Travel Pack, Black
28L capacity
1.02 kg empty weight
15 inch fleece-lined laptop sleeve
Lockable main zippers
Pros
- Lightweight 1.02 kg build with a durable ripstop lining
- Full-wrap suitcase-style zipper opening
- Lockable zippers on the main opening
- Three grab handles and a roller bag pass-through strap
Cons
- 28L is smaller than most carry-on travel backpacks
- Only two main internal pockets
- Water resistant rather than fully waterproof
This is the one you buy when the trip is a week rather than three weeks, and you care about how the thing feels in the hand. At 28 liters and 1.02 kg empty, it is the smallest and lightest-feeling pack here, and the ripstop lining and one-color fabric give it a finish that generic travel packs do not reach.
The opening is the standout. It is a full-wrap zipper that goes suitcase-flat, and inside there is one large, one medium and one small internal pocket, which is a small amount of organisation but well made. The 15-inch padded fleece-lined laptop sleeve sits against your back, so a laptop does not sit in the crush zone.
There are three grab handles, on the side, top and bottom, plus a tuckable waist belt and a roller bag pass-through strap. Lockable zippers on the main opening are a real feature in cities where pickpocketing is a genuine risk, and this connects to our anti-theft travel backpack guide for the full threat picture.

The stretch mesh water bottle pocket takes bottles up to 1 litre, which is larger than anything else here, and there is a front zip accessory pocket with a key clip. Reviewers consistently highlight build quality and light weight as the reasons to recommend it.
At 4.7 across its reviews, satisfaction is high, and the feedback centres on one honest limitation: 28L is a short-trip size.

Best for a one-week European loop
Seven to ten days with laundry is exactly what 28L handles well, and the 1 litre bottle pocket plus lockable zips make it the most comfortable pick in the roundup for a city-heavy itinerary. It is also the easiest to move through a station with, because at just over a kilo there is not much to argue with.
Only two main internal pockets means packing cubes are effectively required for more than a week, and the tuckable waist belt stays flat for a clean carry-on profile.
Where it will not stretch
Two weeks without laundry does not fit. Reviewers consistently position this as a carry-on and day-travel bag rather than a long-trip pack, and the fabric is water resistant rather than fully waterproof, so sustained rain will eventually get through to clothing in a packing cube.
If you need a bigger load, move up to the 40L options rather than forcing this one past its design intent.

The BANGE is the one to look at if your Europe trip is a walking trip rather than a city trip. The fabric is listed as waterproof Oxford rather than water-resistant polyester, and the laptop compartment is a separate waterproof PVC section sized for 17.3-inch machines, which is larger than anything else in this roundup.
It expands from 22 liters to 35 liters through an outer zipper, so it works as a weekender and a week-long carry-on from the same bag. The main pocket takes five to eight pieces of clothing with wet and dry separation pockets, and there are nine pockets in total including a front tech compartment.
At 1.2 kg empty it is among the lighter bags here, and it can be carried sideways like a briefcase using the side handle. Reviewers report it handling three months of Southeast Asia travel and still looking new, and several note it stays comfortable on long carries.

Reinforced bold-line sewing at the shoulder and handle joints is the detail I would point to, because those are the stress points that fail first on cheaper packs. The zippers are smooth and reinforced throughout, which supports the durability reports.

Best for wet weather and walking itineraries
A genuinely waterproof shell and a waterproof laptop compartment are the combination you want in the Alps, in the Dolomites, or on any trip where you will be out in rain for hours rather than minutes. Reviewers with heavy packing reports say the fabric holds its shape and finish when overpacked, which is unusual at this capacity.
The expansion zipper is also a good trick: travel at 22 liters for the outbound flight to stay well inside carry-on limits, then open it to 35 when you have picked up souvenirs or a longer wardrobe.
The trade-offs
There are a lot of loose straps and ties on the outside, and reviewers report that they can block access to the zippers. The compartment structure also feels stiff for the first few trips, so give it a week before you decide it is wrong. The external USB port is only a passthrough, so you need your own power bank.
If you do not need weatherproofing, a lighter 25L pack will serve a city trip better. If you do, this is the one.
How to Choose a Carry-On Backpack for Europe
Match capacity to trip length, not to hope
Most trips to Europe lasting one to three weeks land in the 35 to 50 liter range. A weekend city break fits in 25 liters, a one-week trip sits at 30 to 35 liters, two weeks wants 40 liters, and a month or longer needs 45 to 50 liters or a checked bag. Forum consensus converges on 40 liters as the sweet spot for trips of 20 days or more, with 35 liters for one to two weeks.
Add roughly two litres of slack for souvenirs rather than planning to buy nothing, because that is how people end up with an overstuffed bag at a departure gate.
Check the centimeter dimensions, not the adjective
Carry-on compliance is a measurement, not a marketing claim, and every bag here is listed with dimensions you can check against your airline. The limits that matter most on European routes are Ryanair at 55 x 40 x 20 cm, easyJet at 56 x 45 x 25 cm, and Wizz Air at 55 x 40 x 23 cm. Standard full-service carriers are usually more forgiving than all three.
Keep the expansion zippers closed on the outbound leg, and remember that a bag that fits underseat when lightly packed may not fit once it is full. That is the recurring warning in reviews of the larger 40L models.
The four features that actually earn their place
A clamshell or full-wrap opening lets you pack in a flat rectangle instead of hunting through a deep cavity. Stowable shoulder straps let you set the bag down, slide it into a bin, or lock it in a train rack without loose webbing. A padded hip belt, even a detachable one, moves load off your shoulders on long walking days. And a laptop sleeve is only worth its volume if you actually carry a laptop.
That last point matters. Forum discussion raises the same question repeatedly, and the honest answer is that a dedicated 17-inch sleeve on a phone-only trip is dead volume you could fill with a second week’s clothing. Our larger-bag picks for international trips are covered in the best large travel backpacks guide.
Warranty, anti-theft and the two-bag setup
On warranty, there is a real gap between packs. The Vancropak is the only bag in this roundup listing a lifetime warranty, and owners on the r/onebag forum treat repairability as a decisive trust signal rather than a nice-to-have.
For anti-theft, the realistic threat in cities like Paris, Barcelona, Rome and Amsterdam is bag-slashing and pickpocketing in crowds, not lock-picking. What helps is lockable zipper sliders, a back panel that sits flush against your body, and a front that opens away from you in a crowd. The Vancropak, Lumesner and Cotopaxi all offer some version of that.
On luggage lockers, Europe has no standard. Platform lockers and station racks vary widely, so buy a bag you can carry comfortably in one hand by its top handle, and one that can be locked to a rack. Both the Cotopaxi and the Taygeer have grab handles that make this easy.
Frequently Asked Questions
What size backpack should I take to Europe?
Most trips of one to three weeks work best with a 35 to 50 liter pack. A weekend city break fits in 25 liters, one week needs 30 to 35 liters, two weeks wants 40 liters, and a month or longer needs 45 to 50 liters. Add a couple of liters of slack for souvenirs, and keep expansion zippers closed when flying so the bag stays inside carry-on limits.
What backpacks are popular in Europe?
Carry-on travel backpacks in the 35 to 40 liter range dominate, and the clamshell opening with a stowable harness is the feature European travellers ask for most. The most-repeated recommendations on travel forums are the Osprey Farpoint and Fairview 40 models, with budget options from Decathlon and Quechua frequently named as the lower-cost alternative. The expandable 40L and 35L packs in this roundup are the mainstream budget answer.
Should you carry a backpack in Europe?
Yes, for trips built around rail travel, city stops and cobblestone streets. A backpack keeps your hands free on platforms and stairs, and a soft bag fits overhead bins and train racks far more easily than a hard-shell roller. If you are moving between large cities with metro systems and mostly flat terrain, a small roller case is a reasonable alternative.
Is a backpack ok to bring as a carry on?
Yes. Any soft-sided backpack that fits the published dimensions is accepted in the overhead bin, provided it is not oversized and the expansion zippers are closed. The strictest limits are Ryanair at 55 x 40 x 20 cm, easyJet at 56 x 45 x 25 cm and Wizz Air at 55 x 40 x 23 cm. Measure the packed bag including the harness before you fly.
What not to pack for a Europe trip?
Leave full-size toiletries, hairdryers and clothing irons at home, since they rarely fit the liquid restrictions and many hostel rooms do not have kettles or irons. Do not pack a second pair of heavy shoes, more than one week of clothing, or a hard-shell case that will be checked in on a cobblestone street. Skip anything you would not carry up three flights of stairs.
Our Final Picks for Europe in 2026
The Taygeer 35L is our pick for the best travel backpacks for Europe trips overall. At 0.79 kg with twelve zippered compartments and an underseat-friendly footprint, it handles the gate, the train and the hostel locker without drama, and it is the most-reviewed pack in this roundup by a wide margin.
Go bigger and more versatile with the MATEIN if you need a clamshell opening and straps that fully disappear, or the Tolaccea if you are walking 15 km a day and need a real hip belt. For weatherproofing, the BANGE wins. For repairability over a decade, the Vancropak lifetime warranty is the standout feature.
Whatever you choose, measure the packed bag in centimeters against your airline before you leave home. That single habit prevents almost every expensive surprise on a European itinerary.
