A long-sleeved T-shirt with wind protection is SIXS's solution for winter clothing. Unlike all other windproof garments on the market, SIXS has developed a T-shirt that protects against cold air without creating the greenhouse effect typical of windstopper fabrics. Our technology ensures that sweat does not come into contact with the athlete's skin, and the garment also provides adequate protection for the entire front, which is most exposed to cold air. The back of the T-shirt benefits from the classic SIXS original carbon underwear technology, which keeps the skin free from sweat accumulation. The arms also remain dry and are protected from cooling during physical activities.
