This pair of trousers is part of a four-piece inflight coverall assigned to astronaut Stuart Roosa for use during training prior to his Apollo 14 mission in January 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-coated beta cloth 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.
The jacket had a US flag on the left shoulder and a NASA "meatball" logo on the upper torso. Flight garments also had a mission symbol attached to the upper torso.
NASA transferred this object to the museum in 1979.
This object is not on display at the National Air and Space Museum. It is either on loan or in storage.
