Polartec® Power Stretch®
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 apparel fabrics available today.
Polartec® Power Stretch® fabrics feature a proprietary construction with two unique surfaces: the durable nylon outer layer is wind- and abrasion-resistant; the soft inner layer pulls moisture away from your skin keeping you dry, warm and comfortable. The fabric also features compression stretch which can improve performance and reduces the chance of certain types of stop-go injuries. Polartec® Power Stretch® excels at handling the demands of the next-to-skin environment.
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.

I've had the Power Stretch 1/2 Zip for nearly two years now. It is by far my most versatile piece of clothing. In the Fall, Winter, and Spring, I could easily wear this every day. It's warm enough in the Fall and Spring without being too warm, and it makes for a great midlayer in the winter. I would frequently wear it during Crew practices in college to keep me warm on cold mornings. It would then dry quickly afterwards without keeping any odor. I will definitely be buying more in the future and I highly recommend this to anyone interested in it.
