A backpack for backpacking Europe isn’t just a bag—it’s your mobile lockbox, wardrobe, and office for weeks on end. The wrong choice means aching shoulders, security anxiety, or paying for checked luggage. The right one disappears on your back, glides through airport security, and keeps your gear organized and safe from pickpockets on crowded metros.

Do not waste your trip breaking straps in a hostel. Nothing beats having a secure, comfortable, and carry-on-compliant backpack for backpacking europe that opens like a suitcase and lets you move between trains, hostels, and cobblestone streets without a second thought.
How To Choose The Best Backpack For Backpacking Europe
The difference between a great trip and a miserable one often comes down to what’s on your back. A pack that fits poorly or invites theft will ruin your experience fast. Focus on these three things to get it right.
Capacity and Carry-On Compliance
Aim for 35L to 46L. This sweet spot fits a week’s worth of clothes using packing cubes while staying within the carry-on limits of most European budget airlines like Ryanair and EasyJet. A bag under 22 inches tall is your target. Oversized packs get gate-checked, costing you time and money.
Security Against Pickpockets
Crowded trains, metros, and hostels mean your valuables are vulnerable. Look for a pack with lockable zippers, a hidden stash pocket (like the Thule CashStash), and slash-resistant materials. A bag that opens against your back makes it nearly impossible for someone to unzip it without you noticing.
Comfort and Load Management
You will walk miles with this pack on. A padded hip belt transfers weight from your shoulders to your hips—critical for a 40L load. A ventilated back panel (like Osprey’s AirScape) prevents sweat buildup. Adjustable torso length and sternum straps are non-negotiable for all-day wear.

In‑Depth Reviews
1. Thule Landmark Backpack 40L
The Thule Landmark 40L is engineered for the paranoid traveler—in the best way. Its covert CashStash pocket hides your passport and spare cash under the SafeZone area, completely invisible to anyone glancing inside. The innovative LoopLocks allow you to secure zipper pulls to the bag, turning your pack into a mobile safe. It also features a detachable daypack, letting you leave the main bag at the hostel while exploring with a smaller 20L pack on your back.
This is a two-bag system in one, and the 40L main compartment fits comfortably as a carry-on. The torso length is generous at about 19.5 inches, and the harness is well-padded for long walks between train stations. The main compartment splits into a larger top and a smaller bottom section, ideal for separating clean clothes from dirty gear or shoes. The fabric is lightweight and durable, though it lacks a full waterproof coating—treat it with a DWR spray for heavy rain.
For multi-month or multi-country trips where security is your top concern, the Landmark is unmatched. The daypack clips on and off in seconds, and it fits under a seat when detached. The only compromises are the lack of an outer mesh pocket for a water bottle and the slightly fiddly stowable straps. If you value theft-deterrence and modularity above all else, this is your pack.
Why it’s great
- Hidden CashStash pocket is excellent for passport security
- Detachable daypack provides 2-bag versatility
- LoopLocks secure zippers against pickpockets
Good to know
- No external mesh water bottle pocket
- Stowable straps can be tricky to pack away
2. Osprey Sojourn Porter 46L Travel Backpack
The Osprey Sojourn Porter 46L is the gold standard for international travel. Its Wingjacket compression system uses flexible straps and padded sidewalls to squeeze your load down to carry-on size, and the entire harness—shoulder straps and hip belt—stows away into a zippered pocket, giving the bag a clean, luggage-like profile. This is a lifesaver when you need to check it or stash it in an overhead bin without straps catching on everything.
The clamshell opening is huge and makes packing with cubes effortless. Inside, there are mesh and liner pockets for organization, and a padded laptop sleeve that fits a 16-inch MacBook Pro. The AirScape backpanel is ridged foam with ventilation, keeping your back cool during summer travel. The hip belt is substantial and transfers weight well, but note that the 46L version can be tight as a carry-on for some budget airlines—the 30L version is a safer bet for strict Ryanair limits.
One consistent gripe is the lack of an external water bottle pocket. You’ll need to clip a bottle to the outside or pack one inside. The fabric is tough and durable, but not waterproof. For a bomber pack that can handle months of trains, hostels, and cobblestones, the Sojourn Porter is the proven workhorse. It also comes with Osprey’s TSID luggage tag recovery system.
Why it’s great
- Stowaway harness keeps straps out of the way
- StraightJacket compression adjusts to your load
- Large clamshell opening for easy packing
Good to know
- No external water bottle pocket
- 46L version may be tight for strict EU budget airlines
3. Kelty Redwing Traveler 40L
The Kelty Redwing Traveler 40L is built for the traveler who plans to do more than just city-hop. It features a rigid frame and a substantial, supportive waist belt that makes it genuinely comfortable for a day of hiking or carrying a heavy load through a train station. The 40L size is right at the carry-on limit, and the pack is constructed with heavy-duty polyester and double stitching throughout.
The side pockets are a standout feature—full-length zippered compartments with a secondary pocket behind each one. This is excellent for organizing a rain jacket, water bottle, or travel documents. The laptop compartment has dual access (from the side and the main compartment), which is a rare and convenient design. The pack has seven pockets total, giving you plenty of organizational options without becoming a maze.
At a mid-range price point, the Redwing offers a lot of bag for the money. The main compromises are the lack of a dedicated rain cover (buy one separately) and the shoulder straps, which some users find could be more padded for very heavy loads. For the budget-conscious adventurer who wants a pack that transitions from the hostel to the trail, this is a solid choice.
Why it’s great
- Rigid frame and substantial waist belt for hiking comfort
- Dual-access laptop pocket
- Excellent side zippered pockets for organization
Good to know
- No included rain cover
- Shoulder straps could be more padded for heavy loads
4. Osprey Daylite Carry-On Travel Pack 35L
The Osprey Daylite 35L is the ultralight option for travelers who prioritize speed and simplicity. Weighing just 2.03 pounds, this pack disappears on your back. It features a breathable AirScape backpanel made from mesh-covered die-cut foam, which keeps you cool during long days of walking. The clamshell opening makes packing with cubes a breeze, and the bag is sized to meet carry-on restrictions for most international airlines.
Inside, there is a padded TSA-compliant laptop sleeve that fits a 16-inch laptop and lays flat on the scanner belt—no need to remove your computer. The main compartment has internal and external compression straps to keep your load snug and stable. There are two expandable water bottle pockets on the sides, and a trolley handle pass-through on the back for seamless airport navigation.
The 35L capacity is perfect for a long weekend or a week of minimalist packing. Some users note that it lacks the robust waist belt of larger packs, so heavy loads (over 20 pounds) can put pressure on your shoulders. It also doesn’t have the same organizational depth as the Sojourn Porter. For the traveler who wants to move fast and stay light, the Daylite is a top-tier pick.
Why it’s great
- Ultralight 2.03lb design for easy carry
- AirScape backpanel keeps you cool
- TSA-compliant laptop sleeve for fast security
Good to know
- Lacks a substantial hip belt for heavy loads
- Capacity is smaller at 35L for longer trips
5. tomtoc Travel Backpack 40L
The tomtoc Navigator-T66 40L is an excellent mid-range option that punches above its weight. It is constructed from 100% post-consumer recycled PET plastic bottles, making it a sustainable choice without sacrificing durability. YKK zippers and a water-resistant finish ensure it holds up to rain and rough handling. The size (20.47 x 12.99 x 9 inches) fits within most airline carry-on limits.
The clamshell main compartment unzips like a suitcase, and the TSA-friendly laptop compartment opens 180 degrees for security scanning. Padded shoulder straps and a contoured back panel provide good comfort for its weight class, and an adjustable chest buckle helps stabilize the load. There is also a luggage pass-through strap on the back for attaching to a rolling suitcase.
Several users note that the pack would benefit from a hip belt for heavier loads—the chest strap is helpful but not a full replacement. The recycled fabric, while durable, doesn’t have the same premium feel as higher-end nylons. For the eco-conscious traveler on a budget, the tomtoc 40L offers fantastic value and solid performance for European backpacking.
Why it’s great
- Made from 100% post-consumer recycled PET fabric
- YKK zippers and water-resistant build
- TSA-friendly laptop compartment for fast scanning
Good to know
- Lacks a hip belt for heavy loads
- Fabric doesn’t feel as premium as higher-end nylons
6. Naturehike 45L Rock Internal Frame Hiking Backpack
The Naturehike 45L Rock is a budget-friendly internal frame pack designed for rugged hiking and camping. It features a lightweight 420D nylon build, an ergonomic mesh back panel for breathability, and a dedicated hydration system. The pack also includes a rain cover, which is a critical feature for European backpacking where sudden downpours are common.
The capacity is 40L + 5L (with the extension collar), and the internal frame structure supports loads up to 24 pounds comfortably. The hip belt is more substantial than many budget packs, and the shoulder straps are well-padded. It has multiple compression straps, a dedicated shoe compartment on the back panel, and loops for trekking poles. User reviews confirm it handles 40+ pound loads on multi-day ridge walks without failure.
The main trade-off is the top-loading design. Unlike the clamshell packs higher on this list, the Naturehike 45L requires you to pack from the top, which is less convenient for hostel hopping—you have to dig to the bottom. The roll-top closure is secure but doesn’t allow the kind of easy access a full zip does. If you plan to do serious hiking with your pack, this is a great choice; for pure city travel, look elsewhere.
Why it’s great
- Internal frame supports heavy loads well
- Included rain cover is practical for Europe
- Excellent value for rugged hiking use
Good to know
- Top-loading design is less convenient for hostels
- Roll-top closure limits quick access to gear
7. Tolaccea Travel Laptop Backpack 40-50L
The Tolaccea M03 is a massive, expandable pack that goes from 40L to 50L via a center zipper. It offers a wet/dry compartment, which is rare and incredibly useful for separating damp swimwear or toiletries from your dry clothes. The pack also features a TSA-friendly 180-degree opening for quick security scans, and a padded, side-access laptop compartment for a 15.6-inch laptop.
Construction is surprisingly robust for the price point, with tear-resistant polyester and SBS anti-scratch zippers. The harness includes padded shoulder straps, a breathable mesh back, and a chest strap, plus a detachable waist belt and a crossbody strap for versatile carrying. The pack also has a luggage pass-through strap for use with wheeled suitcases.
This is the most capacity you can get in a carry-on-format without checking a bag. The main downsides are that the pack feels bulky when expanded to 50L, and the organizational pockets are not as refined as premium packs. For the budget traveler who needs to carry extra gear—or who wants a single bag for both the gym and travel—the Tolaccea is a compelling, functional choice.
Why it’s great
- Expandable from 40L to 50L for extra gear
- Wet/dry compartment is great for toiletries
- TSA-friendly opening speeds up airport security
Good to know
- Feels bulky when expanded to 50L
- Organizational pockets are less refined than premium packs
