Normal space suits use oxygen to pressurize the body with 2 tons per square meter at sea level. If in space it is punctured, the body will vacuum freeze in 5 seconds. The Zero Oxygen Space Suit is similar to the Pressure Suit, using artificial muscle fibers to squeeze the body with 2 tons of pressure per square meter. If part of the suit rips only the skin near the rip will freeze. The person inside the suit will remain alive.
