The WTP long johns stand for the new goal in fighting cold. With the help of Brainy Position technology, three different materials are blended into one product. The Winter Barrier (windproof & water-repellent fibre) protects the front area exposed to the cold air from the penetration of the cold & keeps the body warm & dry. In the areas where you sweat more, Carbon Underwear® provides total breathability & heat regulation, while a micro-polar fleece fabric warms & keeps the body in the intermediate areas in the right body heat. Recommended as an intermediate layer, over SIXS Underwear & under other technical overgarments. Features comfort fit Aerofit
