The Milwaukee® FREEFLEX™ Hybrid Work Tee 604 is a long-sleeve work shirt designed to support unrestricted movement, easy layering, and all-day comfort on the job. Made from a lightweight and breathable 4.5 oz cotton/polyester blend, it combines natural stretch with moisture-wicking technology to help manage sweat during long workdays and changing conditions. The forward shoulder design improves comfort while helping reduce wear at high-stress seams, while anti-odor technology helps limit odor buildup. Designed to balance durability and flexibility, this standard-fit work tee is available in black (604B) and blue (604BL).
