Thermo active long johns from Hi-Tec, made in seamless technology from breathable fabric. The inner layer quickly wicks moisture away from the skin, keeping the skin dry even during intense exertion. The outer layer is responsible for thermal insulation and maintaining an optimal body temperature, preventing the body from cooling down. Ankles and hips reduce the risk of cold air getting under the fabric. Wide zones ensure a perfect fit on the figure and guarantee freedom of movement. The irritant fabric is bacteriostatic - it inhibits the formation of dirt odours. Breathable, quick-drying, seamless.
