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 Delron® Flex Frame, the Monster’s got as much built-in engineering as our biggest packs. Hydration compatible? Check. KXO-32™ fabric? Check. Aramid bartacking? Check. Don’t call it a fanny pack: this hip-haulin' S.O.B. just might bite.
