Polartec® Power Stretch®
The fabric is highly breathable and does not restrict the movement of moisture vapor. "Touch Points" on the fabric inner surface draw off the sweat. Sweat is wicked off the skin to the outside of the fabric, where it spreads rapidly for evaporation. When the sweat reaches the outside of the fabric, it spreads out to many times its original surface area, enabling it to dry at least 2 times faster than cotton. The material is wind- and abrasion-resistant and is ideal for next-to-skin use.
