Permanent Polygiene® Odor Control Technology neutralizes odor by stopping the growth of odor-causing bacteria and fungi. The CORE Lightweight Series is the next-to-skin foundation for your high-exertion system, breathing and actively moving moisture away from the skin with its polyester bi-component construction.
