This turtlenecked long-sleeved T-shirt with windproof protection is the solution proposed for winter clothing. Unlike all other windproof garments available on the market, we have developed a shirt that protects you from cold air, but which does not create the greenhouse effect typical of windbreaker clothing. Our technology keeps perspiration away from your skin, and this garment also offers an adequate protection for the whole front, which is the part most exposed to cold air. The back of the shirt employs the classic SIXS original carbon underwear® technology that protects your skin from excessive perspiration. Your arms are also kept dry and warm during the sports activity.
