The Katahdin receives excellent reviews from AT hikers, and has even been to the top of Mt Everest. It offers innovative improvements for ultralite backpacking not found in other packs. The Katahdin’s bottom cinch strap is aligned with the hip belt to provide “in-line” weight transfer to the hips. Three compression straps create a solid “tube-like” structure that replaces the need to use stays. These straps work exceptionally well at minimizing the strain on the shoulders and help to properly transfer weight to the hips -- an impressive feature in a pack that only weighs 26oz! The Katahdin’s hip belt and back panel are made with 1/2” open cell foam with a Cool-Max lamination for added comfort. The compression straps are attached to the pocket wings in such a way as to add greater carrying capacity for the side compartments. Fits torso sizes 19” - 22”. 3,350 cu.in. capacity. Weighs 1 lbs. 10 oz. Made in USA.
