Skylab 4 was launched on November 16, 1973. It was the third and last manned Skylab mission, lasting for over 84 days. The astronauts Gerald Carr, Mission Commander, Ed Gibson, Science Pilot and William Pogue, Pilot, spent Christmas aboard the space station conducting experiments and demonstrations, and studied the sun. They were also able to study and photograph the comet Kohoutek.

This spacesuit was made for and worn by William Pogue, Pilot of the mission and, like the lunar spacesuits, was designed to provide a life sustaining environment for the astronaut during periods of extra vehicular activity or during unpressurized spacecraft operation. These suits 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 was made by the International Latex Corporation with the designation A-7L and was constructed in the Extra-vehicular or EV configuration. The mission symbol attached to the upper left torso indicates Skylab 3, as it was the third manned mission.
