Thermoactive Hi-Tec long underwear with seamless technology made from breathable fabric. The inner layer quickly wicks moisture away from the skin, keeping it dry even during intense physical activity. The outer layer provides thermal insulation and helps maintain an optimal body temperature, preventing the body from cooling down. Pressure-free cuffs at the ankles and hips reduce the risk of cold air entering under the fabric. Wide zones ensure a perfect fit and guarantee freedom of movement. The irritation-free knit is bacteriostatic and inhibits the development of unpleasant odors. Material composition: 66% polyester, 23% nylon, 11% elastane – breathable, quick-drying, seamless.
