6.3-oz Polartec® Power Grid™ | 93% All-Recycled Polyester / 7% Spandex – 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.

Polygiene® Permanent Odor Control – Polygiene® odor control permanently protects your garments from smelling like a middle school locker room. Sweat itself is odorless, but it creates the conditions that bacteria need to multiply, and some of those bacteria produce odors. Polygiene stops the growth of odor-causing bacteria on fabrics, so you can wear more and wash less.
