This pressure suit is an A5-L, developmental Apollo spacesuit, similar to the final design used during the Apollo missions of the 1960s. It was designed and built to prove that this model of spacesuit could provide a life sustaining environment for the astronaut during periods of extra-vehicular activity or during unpressurized spacecraft operation. The suit was not made with a white thermal cover-layer, and has Gemini-style detachable boots instead of the later, integrated Apollo boots.
The spacesuit was made by the International Latex Corporation with the designation A5-L. NASA Manned Spacecraft Center transferred it to the museum in 1972.
This object is not on display at the National Air and Space Museum. It is either on loan or in storage.
