The WTJ jersey represents the new goal in the fight against cold. With Brainy position technology, three different materials are mixed together to form the product. The Winter Barrier (windproof and water-repellent mer) acts in the front part exposed to cold air to keep the cold from penetrating and to keep the body warm and dry. In the portions more subject to perspiration, Carbon Underwear® guarantees total breathability and thermoregulation, while a micro polar fleece weave warms and maintains the right body temperature in the intermediate areas. Recommended as the "intermediate layer", to use on top of SIXS Underwear and underneath another technical outerwear garment.
