The WORKSKIN™ Midweight Base Layer is designed for tradesmen working in cool and cold conditions. This long sleeve base layer dries fast, keeping you warm without restricting movement, whether wearing by itself or comfortably layering underneath an outer layer. You perform at a high level now your shirt will too. Unlike cotton or standard base layers, MILWAUKEE® WORKSKIN™ Midweight Base Layer allows you to wick moisture faster, prevent odor build-up, and easily layer up. The raglan sleeve and stretch fabric let you move freely.
