Polartec Power Shield Pro fabric features great abrasion resistance, and a high warmth-to-weight ratio inner face. The functional layer in the middle enables the fabric to block 99% of the wind. The remaining 1% circulates within the fabric in order to greatly enhances moisture vapor transmission, improving breathability and reducing the risk of heat stress buildup. In fact, Polartec Power Shield Pro fabrics are 30-50% more breathable than windproof soft shells in dynamic or active conditions.
