NASA M-Suit Credit - NASA

In the fall of 1998, two soft suit prototypes were delivered to NASA by two companies, ILC Dover and David Clark. ILC Dover's M-Suit operated at a pressure of 0.26 atmospheres and weighed 30 kg. In comparison to the Apollo and Shuttle suits, the M-suit had a greatest range of motion and the smallest joint torque. It utilized as government furnished equipment the shuttle helmet, neck ring, and wrist disconnects and was designed to interface with the shuttle liquid cooling and ventilation garment, communications carrier assembly, and gloves.
