When it comes to choosing a carry-on backpack for any kind of travel, functionality and durability should be at the top of your list. The Cotopaxi Allpa 35L and the Osprey Porter 46 are both competitive options that you can count on to serve you dependably.

The Cotopaxi Allpa 35L is an efficient travel solution, its bread and butter being the 1680D ballistic nylon paneling. The material is sturdy, while maintain an impressive light weight.

Various reviewers have described the Allpa 35L in glowing terms, with one raving that it's the perfect gift for the "budding world traveler."

On the flipside, the Osprey Porter 46 is designed for those who require more space. With an expanded 46 liters of capacity and a laptop compartment suitable for a 1-inch device, it provides more room to fit your necessities.
