This liner was worn by astronaut Edward "Ed" White, Pilot of the Gemini IV mission that occured in June 1965. The blue nylon liner was the layer of the spacesuit closest to the astronaut's skin, helping to make the Gemini spacesuit surprisingly comfortable.
This liner was a part of the G-4-C spacesuit model designed for Gemini IV. This spacesuit consisted of a cover layer of nylon felt for micrometeoroid protection, seven layers of aluminized Mylar super-insulation and an outer layer of high-temperature HT-1 fabric. The cover garment featured a slipover jacket to minimize bulk during launch, entry, and closed hatch orbital operations.
NASA transferred the liner along with the rest of the spacesuit to the museum after the end of Project Gemini.
