The Dive-SAR is designed as a constant wear, helicopter hoistable harness.  It is constructed the same as the TRI-SAR harness, except for the addition of an upper chest strap.  This additional strap counteracts the weight of a scuba tank, thereby ensuring the slightly reclined, seated hoist position.  Harness is designed to allow the user to wear an integrated or Mae-West style buoyancy compensator.  Size XL.
