Cool-V is a unique technology combining moisture-wicking and cooling properties to provide relief in hot work environments. The proprietary Cool-V fabric pulls moisture away from the skin and absorbs it into the Cool-V fibers; as moisture evaporates it creates a cooling effect to keep workers more comfortable and drier in warm weather. The Cool-V fabric will feel noticeably cooler and can cool the skin by at least 2? F. Hi-Viz, cooling t-shirt,yellow/lime color, short sleeve Sizes Small to 4XL.
