These trousers are part of a four-piece inflight coverall assigned to astronaut Russell "Rusty" Schweickart for his Apollo 9 mission in March, 1969. However, they were never used.
The complete garment consists of jacket, trousers and boots. It is constructed of a Teflon-coated beta cloth, which is highly fire resistant. 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.
Transferred from NASA in 1979.
