"SOKOL-K" Pressure Suit A white nylon canvas suit with royal blue trim, attached pressure hood with hinged, panoramic plastic visor securing to blue anodized aluminum clavicle flange, trussed sleeves with adjustable articulating cables in upper arm and webbed belt lashings, pressure gauge on left sleeve, detachable pressurized gloves, full lace-up front, lace-up crotch with triangular placket, anodized aluminum umbilical interfaces on body for electrical, air and coolant lines with attached cables and hoses, pressure equalization valve below heart, support sling wrapping from chest to back by means of webbed belts and metal clips, metrically calibrated webbed straps attached to metal rings on side seams and along crotch, pleated knees, two utility pockets on each leg, boots of the same material laced on at knee, and a rubberized lining. The tragic decompression accident of Soyuz 11 (1911) in which Dobrovolsky, Volkov and Patsayev suffocated to death during re-entry, precipitated a mandatory return to use of pressure suits during launches, re-entries and docking activities on all Soyuz spacecraft. The newly designed intra-vehicular suit, named Sokol-K ("Sokol-Kosmichesky" or "Space Falcon") was a modified version of the extant Sokol suit. It was the first series to be custom made for each cosmonaut and to be compatible with the individually molded Kazbek shock-absorbing couch used on Soyuz spacecraft. With their integral soft helmets, the suits had a reduced weight of 10km (22lbs.). Even in zero gravity, the cosmonaut could dress himself in only a few minutes. Engaging the life support systems took only 30 seconds: air and oxygen are fed to the suit via the ventilation and oxygen hoses which are connected to the onboard life support system; oxygen is delivered only to the helmet portion of the suit. Although the Sokol-K suit was available for use in 1972, and was tested onboard Soyuz 12 in 1973, the first full-fledged use in space occurred with the Apollo-Soyuz mission in 1975. The spacesuit continued to be used through 1980. Although this suit was not designed specifically for a particular cosmonaut, it remains an important part of space history, is complete in all respects and is in excellent overall condition.
