Polartec® Power Shield® Pro
Adding real water resistance to their soft shells with the launch of Polartec® Power Shield® Pro, Polartec® is combing never before seen levels of air permeability with durable hydrostatic resistance to keep wearers dry from both within and without. Polartec® Power Shield® Pro fabrics feature a smooth, tightly-woven face for great abrasion resistance, and a polyester back for a high warmth-to-weight ratio. The membrane in the middle enables the fabric to block 99% of the wind. The remaining one percent circulates within the fabric, greatly enhancing moisture vapor transmission, improving breathability and reducing the risk of heat stress buildup.
