3.8-oz Polartec® Power Grid® with Polygiene® Permanent Odor Control – Polartec® Power Grid® was created to push the performance of base fabric technologies even further. By developing a patented grid design structure Polartec discovered a new way to reduce fabric weight while increasing warmth and compressibility in the process. This grid construction enhances both wicking efficiency and breathability by generating channels of targeted touch points that absorb and diffuse moisture vapor for faster evaporation.
