Weighing 90 kg (198 lb), the suit could operate for 10 hours before requiring a resupply of consumables, and had a total operating lifetime of 48 hours. The Krechet was the first semi-rigid space suit ever developed, with an

The suit featured a chest-mounted control and instrument panel which could fold out for use or fold flat against the chest when not needed. The suit also featured a metal "hula hoop" ring on the back, which would allow a solo cosmonaut who fell on his back to roll onto his side and use his arms and legs to stand. The suit had two snap-down visors, providing differing levels of sun protection, in addition to a clear visor. The outer visor was coated in gold for reflectivity.
The suit was designed to be worn over a liquid cooling garment. The inner fabric of the suit was gray nylon canvas. The suit was insulated with waffle-textured foil. The outer layer was an off-white satin-weave fabric with orange trim.
Because of constraints in shoulder and elbow mobility in the Krechet, the Soviet lunar lander featured a "finger controller" which allowed a suited pilot to operate the lander. The Krechet would have served as a microgravity suit as well as a surface suit, as the Soviet lunar lander (LK) and command module (LOK) were not designed for intravehicular crew transfer.
