These trousers are part of a four-piece inflight coverall garment assigned to astronaut Eugene Cernan for use during his Apollo 17 mission in December, 1972. However, the garment was never used.
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 to the National Air and Space Museum from NASA in 1978
