Comfortable, warm technical underwear made for skiing and snowboarding. The sweater has a round collar with snap opening, chest pocket and a casual inspired design. It will work well directly on the skin or with a thin layer under. The brushed polyester tech+ fabric has a Polygiene® treatment for less smell, and is very comfortable and warm on the skin, with good elasticity.
