Our 100% acrylic rib-knit Watch Hat. Carhartt customers have been counting on this knit favorite for years. It's a comfortable one-size-fits-all that knows how to keep you warm. The Carhartt logo is sewn in and featured on the front. The hat comes in several great colors -- something to coordinate with just about any and all of our other work and casual wear -- plus bright lime and bright orange that help you stay in easy sight in darker conditions.
