This spacesuit was worn by astronaut Neil Armstrong, Commander of the Apollo 11 mission, when he became the first man to walk on the Moon on July 20, 1969.
The lunar spacesuits were designed to provide a life sustaining environment for the astronaut during periods of extra vehicular activity or during unpressurized spacecraft operation. They permitted maximum mobility and were designed to be worn with relative comfort for up to 115 hours in conjunction with the liquid cooling garment. If necessary, they were also capable of being worn for 14 days in an unpressurized mode.
The spacesuit has the designation A-7L, and was constructed in the Extra-vehicular or EV configuration.
