The A-7L Spacesuit

The Apollo lunar spacesuit was designed to provide a life sustaining environment for the astronaut during periods of extravehicular activity or during unpressurized spacecraft operation.

Materials

were designed with a white, non-flammable material called beta cloth, a Teflon-coated fiberglass. 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.

81 pounds

is how much this type of suit weighted on Earth when the primary life support system (PLSS) was attached.

-250°F to +230°F

is the range of temperatures the suit protects against.

EMU repair kit

was a maintenance kit carried by the Apollo 11 astronauts to make minor repairs to their spacesuits. It contains cloth tape, exterior patches, sealant bladder repair material, optical surface cleaning and defogging pads, and replacement gaskets.

25 layers

of protective materials make up the suit.

The overshoes

(worn only on the Moon) and portable life-support systems were left on the lunar surface to reduce launch weight.

Iconic

Apollo 11 made the A7L the most iconic suit of the program. It proved to be the primary pressure suit worn by NASA astronauts for Project Apollo.
