Polartec® Power Stretch®

Material Description
Fabrics made from Polartec® Power Stretch® are bi-elastic and have particularly good breathability. They keep the body dry during physical exertion and offer warmth without the weight. Many of these materials have a patented knit construction with two different surfaces: the robust outside is wind-resistant and rub-resistant, while the soft inside absorbs dampness from the skin and keeps the wearer pleasantly dry and warm. All Polartec® Power Stretch® materials are best worn directly next to the skin. www.polartec.com
Power Stretch® Pro™ This new material consists of sturdy polyamide yarns. Fabrics made of Polartec® Power Stretch® ProTM are bi-elastic and have particularly good breathability. They keep the body dry during physical exertion and offer warmth without the weight. Many of these materials have a patented knit construction with two different surfaces: the robust outside is wind- and abrasionresistant, while the soft inside absorbs dampness from the skin and keeps the wearer pleasantly dry and warm. All Polartec® Power Stretch® ProTM materials are best worn directly next to the skin.
How does it work?
Moisture and high relative humidity next to the skin cause discomfort. Polartec® Power Stretch® keeps the skin dry through three complementary mechanisms:
1) The fabric is highly breathable and does not restrict the movement of moisture vapor.
2) "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.
3) 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.
