The MILWAUKEE Men's X-Large Gray WORKSKIN Midweight Base Layer Long Sleeve Performance Shirt is designed for tradesmen working in cool and cold conditions. This long sleeve base layer dries fast, keeping professionals warm without restricting movement, whether wearing by itself or comfortably layering underneath an outer layer. Professionals perform at a high level now their shirt will too. Unlike cotton or standard base layers, the WORKSKIN Midweight Base Layer wicks moisture faster, prevents odor build-up, and is easily layered up. The raglan sleeve and stretch fabric move freely.
