This RX-2-A Advanced Extra-Vehicular Suit is an experimental constant volume suit was manufactured by Litton Industries who made a series of "hard" suits during the early 1960s. These experimental suits were designed to maintain an almost perfectly constant volume while enabling a full range of body motions. They could operate at higher pressure, thus reducing the time-consuming oxygen pre-breathing period before extra vehicular activities.
It has more sophisticated shoulder joints than the RX-2, and closes with a dual-plane closure at the back. It operated at 5psi instead of the 3.7psi of the Apollo soft suits.
