These trousers are part of a four-piece inflight coverall garment used by astronaut Alan Shepard during his Apollo 14 mission in February 1971.
The complete garment consists of jacket, trousers and boots which had a circular Velcro patch on the soles. It is constructed of a Teflon fabric which is highly fire resistant, and the "slippery" qualities of the fabric enabled the astronaut to don and doff the garment with ease in a weightless environment.
Transferred from NASA to the National Air and Space Museum in 1979.
