This suit was manufactured by Litton Industries, which made a series of "Advanced Extra-Vehicular Suits (AES)" during the early 1960s that were of a constant volume whether pressurized or unpressurized. This one is a "hybrid", identified as the Model B1-A, of which approximately six were made, and was not equipped with a thermal cover-layer. It had a hemispherical helmet made of polycarbonate.

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.

Transferred to the National Air and Space Museum from NASA in 1979
