The Cotopaxi Allpa 35L impresses with a well-design internal organization that is intuitive and helpful, and includes a rain cover, a collapsible laundry bag and a nylon shoe bag among other accessories.

The Hynes Eagle 40L, on the other hand, stands out for its TSA-friendly tech compartment, multiple compartments for organization and the ability to compress down to 30L for a lighter, slimmer profile.
