Best 30-40L Travel Backpacks for One-Bag Trips (Tested)


Traveling with just one bag seems impossible, but the right backpack makes it easier. A good 30-40 liter bag holds everything you need for a week or more, fits in the overhead compartments and leaves your hands free to explore. We’ve tested dozens of travel backpacks to find the ones that actually work for real-world travel, from weekend city breaks to international adventures.

The Allpa is popular for its suitcase-style shell and internal mesh compartments that keep everything visible and tidy. Opening it is like opening a bag: you see all your gear at once instead of digging into a dark hole.

The latest version uses 100% recycled fabrics, adds a water bottle pocket and cargo pass-through, and still weighs 2 pounds, 15 ounces. It’s incredibly light for such a well-organized bag.

Stellar organization in a lighter-than-average case, with a durable TPU coated exterior for travel.

A stylish and durable 35 liter carry-on bag designed for city travel and technology enthusiasts. You get a hanging 16-inch laptop pocket that protects your computer from impact, a lay-flat main compartment, multiple quick-access pockets, cargo lifts, and grab handles all around.

The X-Pac version weighs 3.9 pounds and uses sailcloth that resists rain and rough handling. Every pocket has a purpose, from passport slots to cable organizers.

Premium construction, excellent technical protection, and room for everything without feeling complicated.

When you want to carry everything in one bag without straining your shoulders, the Tortuga’s height-adjustable harness and cushy hip belt shine. This bag packs like a suitcase, uses water-resistant ECOPAK sailcloth, and weighs 4.5 pounds, a compromise for the plush suspension that frequent walkers appreciate.

The harness adjusts to fit torsos from 15 to 22 inches, so it sits directly on your back. This means that the core supports most of the weight rather than your shoulders.

The most backpack-like carry in a travel bag; the harness relieves the load during long transits.

If you want a proven, versatile travel bag that stays light on your back, this is it. The Farpoint 40 is carry-on sized, has a support frame with load risers, an external toilet pocket for security lines, and a 16-inch laptop sleeve.

Weighing just 3 pounds 6.4 ounces, this bag balances comfort and reasonable weight. Osprey built it specifically for travelers who walk between gates, trains and hostels.

The comfort and structure for longer walks between gates and stations, plus the Osprey’s user-friendly layout make it worth it.

Sometimes you just want a simple, lightweight bag without all the bells and whistles. Cabin Zero offers just that with its 36-liter Classic bag, which weighs an astonishing 1 pound 9 ounces, less than half of what most travel bags weigh.

The design is simple: one main compartment, a few pockets, padded shoulder straps and carrying handles. No frame, no fancy suspension, just a well-made bag that meets carry-on size limits worldwide.

Ultralight simplicity for minimalist travelers who pack light and don’t need rugged features or extra organization.

Can’t decide between a sports bag and a backpack? Eagle Creek solved this problem by making both in one bag. The Gear Warrior gives you backpack straps when you need them and stows them away when you prefer to carry it like a gym bag, and it also has four grab handles positioned around the bag.

Weighing 3 pounds 7 ounces, it uses abrasion-resistant fabric and a wide clamshell opening. The hybrid design works surprisingly well for travelers looking for flexibility in how they carry their gear.

Versatile carrying options and sturdy construction for travelers who want to choose how they carry their belongings.
