This fleece has the highest warmth-to-weight ratio in the ski/snowboard category. Its made with Polartec® High Loft, and is thus warm within a shell, with excellent moisture transportation. Polartec® Power Dry® on the sides and underarms ensures flexibility and a close fit. When used as outer wear, the jacket breathes and dries easily due to the open knit of the fabric, but it is not wind-protecting.
