Polartec® Power Dry® fabrics are designed to keep your skin dry when you sweat. All fabrics in this series feature a patented bi-component knit construction that uses different yarns on either side of the fabric. This creates two different surfaces: one that is optimized to move moisture away from the skin, the other to dry quickly. Ideal Uses: Polartec® Power Dry® fabrics are highly breathable, and are ideal as the base layer for all sports, either as underwear or technical shirting.
Function: Moisture and high relative humidity next to the skin cause discomfort. Polartec® Power Dry® keeps the skin dry through three complementary mechanisms:
- 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. Polartec® Power Dry® fabrics move at least 30% more moisture away from the skin than single component fabrics.
- 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.
