Abstract: A resilient back pack supporting member for carrying loads, particularly for hikers or mountaineers. The resilient supporting member is triangular in cross-section, with the thinner top portion designed to contact the shoulders and the thicker bottom portion designed to contact the lower back of the wearer. The support is fastened to the back by conventional shoulder straps, with the load strapped or otherwise secured to the external rear surface. In one embodiment, the support may be formed of a single triangular slab of foam rubber or the like, covered with a cloth skin. In another embodiment, the interior of the supporting member is stuffed with chips or small pieces of foam rubber or the like. In a third embodiment, the skin is a gas impervious bag which is pumped full of air or oxygen through conventional valve means.
