Long Sleeve Workwear Henley by Carhartt. Long sleeve workwear Henley is an all-purpose work shirt that is perfect for cooler days or as a layering piece. Made of 6.75-ounce, 100% cotton jersey, it features a rib-knit collar with a three-button closure and a left chest pocket. It also has side-seamed construction to minimize twisting and maximize comfort. For a slimmer fitted look we recommend going a size down from your normal size.
