Milwaukee WorkSkin Performance shirts are designed for tradesmen that need their next-to-skin layer to dry fast, keep them cool, and protect them from the sun in hot, summertime working conditions. Unlike cotton or standard wicking shirts, Milwaukee WorkSkin performance shirts utilize patented COOLCORE fabrics to stay up to 30% cooler, wick moisture faster, and prevent uncomfortable saturation from sweat. The addition of fast wicking sweat zones underneath the arms and down the back help accelerate drying in high-sweat areas. Made with fabrics that resist pilling and snagging from repeated daily use, Milwaukee WorkSkin performance shirts stay dry and stay cool to reduce fatigue from the hard work in the heat.
