This suit is an example of an XMC-2 full pressure suit developed for use in the mid-1950s jointly by Wright Field personnel and David Clark Co. for X-15 pilots. It represented a major advance in pressure suit technology serving as prototype for those used later by Mercury and Gemini astronauts. It allowed the wearer freedom of movement while keeping him comfortable and protected in the event of cabin pressure failure or emergency ejection from the X-15 at extreme altitudes. The suit incorporated a ventilation layer to cool the user and an outer heat resistant layer. The helmet was built by the Bill Jack Co. and contained oxygen equipment, a microphone, earphones and an anti-fogging feature.
