For this guide, we evaluated five travel backpacks across key criteria: carry-on compliance with major airlines, overhead-bin fit, organization, harness comfort for long transit days, and overall durability.
Quick verdict
Buy the Osprey Farpoint 40 unless you have a reason not to — it is the best balance of comfort, capacity and compliance. The Tortuga Setout 45L is the better bag if you value structured organisation and mostly fly carriers with generous limits.
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

|---|---|---|---|---|
| Osprey Farpoint 40 | 40L | 1.6 kg | Yes | Trips under 2 weeks |

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.
Who this is for
- One-bag travellers avoiding checked luggage fees and baggage carousels
- Trips of a few days to a few weeks where you can do laundry
- Travellers combining city stays with some walking between accommodation
Who should skip it
- Anyone needing formal clothing to arrive uncreased
- Long expeditions requiring specialist or bulky equipment
- Travellers who prefer wheels, where a roller case is easier on paved ground
Final verdict
Pick on how you pack. The Farpoint suits people who use packing cubes and want one open space; the Setout suits people who want the bag to do the organising. Both beat a roller case the moment you meet stairs or a cobbled street.
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.
