A belt-supported backpack has been devised which is adapted to be worn around a person's waist and fully supported over the pelvic region of the wearer so as to avoid necessity of cumbersome frames or shoulder straps. The belt proper is formed of an elongted flexible length of material which has forwardly tapering free ends adapted to be releasably secured together and the intermediate portion of the belt forms the inner wall or lining of the backpack or main compartment of the backpack. Most desirably, the main compartment has a releasable closure along the sides and top to permit it to be fully opened, and an auxiliary compartment on the outer wall of the main compartment has separate releasable closures which open into a common interior. One of the releasable closures on the side of the auxiliary compartment is so constructed and arranged as to permit ready opening by the wearer simply by reaching behind and forcing open with the hand without necessity of releasing the belt. Reinforcement straps are also provided on the belt to cooperate in securely fastening the belt around the waist.
