Summary
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 was called 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.
NASA transferred the suit to the National Air and Space Museum in 1979.
