Abstract : Three types of exposure suits for underwater swimmers were evaluated in the Arctic Ocean at water temperatures between 28.9F and 30.6F: a 3/8-inch thick, closed cell neoprene, standard wet suit; a 1/4-inch thick, closed cell neoprene dry suit worn over full nylon fur underwear; and a 3/8-inch thick wet suit fabricated of noncompressible material. Four diver-oceanographers used and evaluated the suits in subfreezing water beneath the ice. It was concluded after a series of 40 dives, ranging in duration from 37 to 115 minutes, that the dry suit affords more protection and is more satisfactory than either wet suit. The wet suit of noncompressible material provides more protection at depth than the standard wet suit. None of the gloves or mittens, or any combination, afforded adequate protection for the hands.
