Take on the tough jobs in the quality and comfort of Carhartt's flame-resistant work shirt. Constructed of 6-ounce FR twill (a durable blend of 88% cotton and 12% high-tenacity nylon), it features main seams that are triple stitched for added strength. Anti-odor fabric treatment keeps you fresh through all-day work. This button-down shirt stores items securely in two chest pockets with button closures. Two-button adjustable cuffs help ensure a great fit. FR melamine buttons are used throughout. VPN: 100168.
