MC-1

American pressure suit, operational 1956. Modified S-2 partial pressure capstan suit with chest breathing bladder, 12 sizes, high altitude, fighters and bombers, smaller capstan in torso area, pressure gloves, K-1 or MB-5 helmet, David Clark Company.

All the early partial pressure suits were extremely tight fitting and therefore quite uncomfortable in prolonged use. The reduced comfort of the so-called "Henry suit" was an unfortunate aspect of subsequent developments of the T-1 and S-2 suits, designated the MC-1, MC-3 and MC-4 series models (the MC-2 type suits were experimental full pressure suits). However the suits did accomplish their main purpose -- to protect the wearer from the effects of emergency decompression at altitude.
