This is more than a "fanny pack." The Monster&';s adjustable suspension keeps everything in place. With 1,100 cubic inches of storage, seven pockets, and a DelronA(R) Flex Frame, the Monster&';s got as much built-in engineering as our biggest packs. Hydration compatible? Check. KXO-32(TM) fabric? Check. Aramid bartacking? Check. Don&';t call it a fanny pack: this hip-haulin&'; S.O.B. just might bite.
