This A1-C spacesuit was worn by various astronauts during early training sessions for the Apollo missions. The A1-C spacesuit was a modification of the Gemini G3-C and G4-C spacesuits. In 1966 NASA had decided to use the A1-C design for Earth-orbiting Apollo missions. After the Apollo 204 fire in 1967, NASA decided to abandon the A1-C design entirely and use what would eventually become the A7-L Apollo suit for all missions.
It consisted of five major assemblies, the main suit, helmet, boots, gloves and neck seal. The astronaut was equipped with a life vest assembly, and wore a cotton constant wear garment underneath the suit. The suit weighed approximately 25 lbs, was relatively comfortable and permitted freedom of movement while pressurized.
The A1-C suit was made by the David Clark Company, and NASA transferred it to the National Air and Space Museum in 1973.
