This garment will keep you warm whether you are hunting, fishing, motorcycling, or snowmobiling or any other outdoor activities. Polartec® Power Stretch® provides body-hugging four-way stretch for maximum freedom of movement in any activity. Worn either alone or as first layer underwear, it provides superior thermal insulation with less weight than other fabrics. Both durable and pill -resistant, its nylon face and thermal inner surface make it ideal for rugged, active cold weather sports. Don' t forget to add in good looks and easy care. Power Stretch® is a machine -washable blend of polyester, nylon and lycra. 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. Black Only Sizes: S-XXL 100% Made in USA
