A carry-on backpack lets you skip the checked bag and keep your things with you. This comparison puts four travel packs from Osprey, Tortuga, and Peak Design side by side on capacity, size, weight, laptop storage, carry system, and warranty.
How We Chose
We compared four carry-on travel backpacks from Osprey, Tortuga, and Peak Design. All four packs are available on Amazon. We left out cheaper backpacks from little-known brands. The packs are not identical. Capacity ranges from 35L to 45L, and the Farpoint 40L is listed as a men’s specific fit, so the packs differ and where a value was not stated in the fields we checked we say so. Airline carry-on limits vary, so check your airline before you rely on any listing. Capacity, size, weight, laptop storage, and warranty figures come from each manufacturer’s own pages where we could read them, and each table cell names its source. Where a manufacturer page names the exact model, we use its figure instead of the Amazon listing. This is a researched comparison, not a hands-on test, so we make no claims about comfort or how much each bag really holds beyond what each listing says. Prices are Amazon prices checked in September 2026 and can change.

Check Price on Amazon →Our Take
If price and weight matter most, the Osprey Daylite Carry-On at 35L is the lightest and least expensive. If you want a 40L pack with a harness that stows away, the Osprey Farpoint is the middle option. The Tortuga lists the clearest carry-on dimensions and the Peak Design is the only expandable one, at the highest price. Both Osprey packs and the Tortuga and Peak Design packs have long-term manufacturer warranties, but the terms differ, so read them before you buy. Always check your airline’s carry-on limits. We did not test any of them.
