Carhartt's long sleeve Work-Dry mock turtleneck can be worn alone or layered. It's made of 6-ounce, 60% cotton/40% polyester Work-Dry fabric, which wicks away moisture for comfort and has an anti-odor treatment. It also has rib-knit cuffs and collar, side-seamed construction to minimize twisting, left chest pocket with logo label, rolled forward shoulder for a more nice fit and a tagless neck label.
