A durable layer for chilly weather, this Jac-Shirt is made with the unwaxed version of our iconic canvas that’s sheltered foresters and sportsmen in the backcountry for a century. The 10.5-oz. 2-ply by 2-ply cotton duck canvas is renowned for its exceptional abrasion resistance. Treated with a long-lasting DWR, it repels light rain and resists staining. An extra layer over the front shoulders provides additional protection and hides the two snap-secure chest pockets. The side-entry hand pockets are easy to access and are bar-tacked for durability. The metal snaps used for the adjustable cuffs and front closure are virtually unbreakable, and easy to operate while wearing work gloves. Side-seam slits provide greater ease of motion.
