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.
