Polartec® power stretch® fabrics feature body-hugging 4-way stretch and are very breathable. They keep you dry when you sweat and provide warmth without weight. These are the most versatile outdoor and fitness clothing fabrics available today. Many of the fabrics feature a proprietary construction with two unique surfaces: the durable, smooth outer layer is wind- and abrasion-resistant; the soft inner layer pulls moisture away from your skin keeping you dry, warm and comfortable. Other fabrics in the series feature compression stretch which can improve performance and reduces the chance of certain types of stop-go injuries. Climbing, running-even taking on an Ironman competition – are easier when your clothing doesn’t inhibit freedom of movement.
Moisture and high relative humidity next to the skin cause discomfort. Polartec power stretch keeps the skin dry through three complementary mechanisms:
• The fabric is highly breathable and does not restrict the movement of moisture vapour.
• “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 swear 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.
