Liquid Cooling and Heating Garment (LCHG) is a protective garment for human spaceflight. It is a close fitting long garment that covers the torso as well as the limbs from neck to toe as a single piece lightweight comfort inner wear. The flight suit has to be worn by the astronauts over the LCHG. The garment permits the long term use without any impact on the wearer in terms of skin irritation or infection.
