This design was a derivative of the Sokol-K suit, with this model having a transverse zipper at the waist to allow for easier on and off capabilities, as well as making it more customizable to individual cosmonauts’ sizes. Designed as a ‘rescue suit,’ it kept the astronaut alive in case of accidental depressurization of the spacecraft. Suit appears to be complete with helmet, boots, gloves, and cables. A manometer is attached to the upper arm, and several patches are sewn to the upper torso. RR Auction COA.
