Development began in 1967, concurrently with the Orlan suit for microgravity spacewalks.
The Krechet was the first semi-rigid space suit ever developed, with an aluminum alloy hard upper torso and soft fabric limbs.
The Krechet included waist and hip joints which were not present in the Orlan.
The shoulders and wrists of the suit included ball-bearing joints, which allowed for almost 360 degree rotation.
The rear-entry hatch concept is attributed to Zvezda engineer Anatoli Stoklitskii.
