Abstract
Underwater breathing apparatus including a diver worn back pack having a hard outer shell and a soft flexible undersurface to conform to the diver's back. Breathing bags positioned between the undersurface and outer shell are connected to the undersurface so as to extend down the diver's back and be coextensive with his lungs. Gas circuit components are mounted on the inside of the shell. The apparatus makes contact with the diver's back, at a small area on the upper portion of his back, and, at the lower portion of the diver's back two extending projections from the shell receive a transverse strap which contacts the diver in the vicinity of the small of his back.
