Best Travel Backpacks for Carry-On Travel

The Farpoint 40 is the easiest recommendation because it balances capacity, carry comfort and a suitcase-style opening. The main compartment opens flat, so you can pack it like a duffel or a small suitcase, and the internal compression straps keep a half-empty bag from collapsing. A padded hipbelt and shoulder straps make it comfortable for longer walks between stations and hotels, which is where many travel backpacks fall down. The 40 L size is widely accepted as carry-on, though you should still check your airline's sizer.

The Allpa 35L treats organization as the main feature. Its clamshell body is divided into zippered mesh compartments, so clothes, shoes and small items stay separated without packing cubes. The harness tucks away behind a panel, which makes the bag easier to handle on buses, trains and overhead bins, and a rain cover is included. The trade-off is capacity: 35 L is enough for a short trip or a disciplined packer, but it is tighter than the 40 L and 45 L options here.

The Peak Design Travel Backpack 45L is designed around access. It opens from the back, the side and the front, so you can reach a camera body, a laptop or a layer without unpacking the whole bag. The bag compresses down when you are carrying less and expands when you need the full 45 L, which makes it more flexible than a fixed-volume pack. It adds more hardware and more straps than a basic clamshell, but for a photographer or a remote worker carrying several devices it earns that complexity.

The Black Hole MLC 45L is the pick when you want options. It works as a backpack, can be carried over one shoulder, and has grab handles for hauling it like a duffel. The clamshell opening gives you suitcase-style packing, and the Black Hole fabric is built to shrug off rough handling on buses, boats and baggage belts. It is not as refined a hiking-style carry as the Osprey, but it is more versatile across different kinds of trips.

The Tour Travel Pack 40L keeps things straightforward: a clamshell main compartment, a manageable 40 L capacity and a harness that is comfortable enough for transit days without the bulk of a trekking pack. It suits travelers who pack in cubes and do not want a web of built-in compartments. If you want a clean, simple bag and do not need camera-specific access, this is a sensible alternative to the Farpoint.
