With thousands of miles and hundreds of animals on our frames, we have rolled 30+ years of experience in the backcountry into our new ARK Frame. The ARK Frame is made with the best possible materials for the application. We use Carbon Fiber, high density nitrogen enriched foams, and laser cut reinforced MOLLE to solve a lot of the problems our past offerings experienced. Made in two sizes, the 25” and 22” will accommodate all torsos and expeditions. The ARK Frame is compatible with most of our legacy Duplex packs and the all-new Loop Lock strap attachment system will make strapping quarters and other awkwardly shaped items much easier.
