The Condor Bison Backpack is an upgrade from our old Assault and Shoulder bag, integrating the sling as a pouch that can be attached or detached. It features a large compartment that uses a U-Shapped opening which allows you to grab things from the bottom of the bag without having to sacrifice the organization you worked hard to achieve. Also it features webbing on the front panel for extra pouches incase you need more than the additional sling bag. The Bison is per- fect for any city exploration or hiking excursion.
