Pressure Suit, A7-LB, was made for, and worn by James Irwin, lunar module pilot of the Apollo 15 mission that landed in July, 1971. This was the first mission to use the lunar roving vehicle. The spacesuit was designed to provide a life-sustaining environment during periods of extra vehicular activity or during unpressurized spacecraft operation. It optimized mobility and was designed to be worn with relative comfort for up to 115 hours in conjunction with the liquid cooling garment.

It all weighed approximately 185 pounds here on earth.
Why were spacesuits custom fitted?
Spacesuits were custom fitted to ensure optimal mobility and comfort.
Spacesuit Zippers
The locations of the zippers on Irwin’s spacesuit differ from earlier suits. Two zippers - one acting as a restraint and the other that is the pressure-sealing zipper - run from the upper front of the chest around the waist to the lower chest.
Spacesuit Joint Sections
Convoluted joint sections of rubber were located in the shoulders, elbows, knees, hips and ankles. This enabled relatively easy movement while the suit was pressurized.
Spacesuit Life-support Ports
The location of the communication and life-support ports differ from earlier spacesuits. When combined with the portable life support system and other components making up the extravehicular mobility unit, it all weighed approximately 185 pounds here on Earth.
