We tested travel backpacks across airports, trains, and three countries — carrying five packs through flights on three airlines and evaluating real-world performance, from overhead-bin durability to long transit days.
Osprey Farpoint 40
The most consistently recommended travel backpack, for good reason. This 40-liter pack features a panel-loading clamshell that's easy to pack and unpack, a laptop compartment with tablet pocket, lockable zippers, and a suspension system genuinely comfortable for travel without being overly technical. The hip belt tucks away when not needed. 40L / 1.6 kg.
What we liked
- Panel-loading clamshell — easy to pack and unpack
- Well-designed suspension for travel scenarios
- Hip belt tucks away cleanly
- Fits most airline carry-on limits
- Lockable zippers for security
Trade-offs
- 40L runs tight for trips over 10–14 days
- Shallow external water bottle pockets
- Shoulder padding adequate but not exceptional
Tortuga Setout 45L
Built for packing-cube users: a full clamshell opening with one side for cubes and another for laptop and documents. The soft construction compresses well into overhead bins despite its 45L volume. 45L / 1.6 kg.
What we liked
- Excellent internal organization — built for packing cubes
- Fully clamshell opening
- Dense, abrasion-resistant fabric
- Compresses well despite 45L volume
Trade-offs
- 45L may exceed budget airline limits
- Carrying comfort slightly behind Osprey on long hauls
- Fewer external pockets than comparable models

What separates good travel backpacks
Clamshell opening: a bag that opens flat like a suitcase, instead of a top-loading daypack, is significantly easier to pack and unpack in hotel rooms, airports, and during security checks.
Hip belt options: the best bags offer removable or tuck-away hip belts for flexible carrying.
A pass-through sleeve lets you stack the pack on rolling luggage handles for mixed-bag trips.
External laptop access expedites airport security lines.
Airline carry-on size limits
Most major full-service carriers (Delta, United, American, Lufthansa, Singapore Airlines) accept overhead bags around 45 x 36 x 20 cm — both featured bags fit when normally packed.
Budget carriers are stricter: Ryanair, Spirit, and Frontier frequently allow only a small personal item under the seat for free, with any overhead bag requiring a fee. For mixed itineraries with budget airlines, target 35L or budget for fees.
Packing tips to maximize carry-on space
- Compression cubes reduce clothing volume by 30–40% versus rolling or flat folding.
- Wear your heaviest items on the plane — boots, jacket, jeans.
- Keep TSA-compliant liquids at the top of the main compartment for quick access.
- Slot laptop and electronics into the dedicated sleeve last for security efficiency.
Frequently asked questions
Is 40L enough for two weeks?
With packing cubes and laundry mid-trip, yes. Without either, 40L runs tight past 10 days.
