Polartec Power Grid

Polartec® Power Grid™ Less is more: The primary insulation layer among experienced outdoor enthusiasts for nearly two decades, Polartec® fabrics are available in a variety of unique textures and weights designed specifically to enhance performance in a variety of environs. Polartec® Power Grid™ features a patented grid design structure to reduce weight while increasing warmth and compressibility. Moisture is continuously pulled from your skin and diffused to the outside, where the exterior layer then spreads the moisture out to a wider surface area for faster evaporation.
