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 and water-repellent fibre) protects the front area exposed to the cold air from the penetration of the cold and keeps the body warm and dry. In the areas where you sweat more, Carbon Underwear® provides total breathability and heat regulation, while a micro-polar fleece fabric warms and keeps the body in the intermediate areas in the right body heat. Recommended as an intermediate layer, over SIXS Underwear and under other technical overgarments. Features comfort fit Aerofit
