Cooling suit including legs, torso and arms, which includes outwardly opening hose sleeve in the hip area, inwardly branching gas ducts having several outlet openings. A pressurized gas cylinder for carrying along and connecting outlet hose with coupling piece to this hose sleeve, and which comprises a valve and adjusting wheel for the regulated delivery of expanded gas into these gas ducts. The gas ducts in the upper-body have outflow openings in the area of the lower back, hips, neck area, armpits, arm joints, and sleeves. In the lower-body garment, outflow openings are arranged in the knees and the crotch area. This cooling suit is operated with a dry, compressed gas. The gas flowing from the pressure cylinder is expanded, subsequently cools down and then flows through the gas ducts and cools the body. Perspiration is carried away by the permanent gas supply via the breathable fabric of the suit.
