Take on the tough jobs in the quality and comfort of Carhartt's flame-resistant work shirt. Constructed of 5.8-ounce FR twill (a durable blend of 48% modacrylic, 37% lyocell and 15% aramid), it features main seams that are triple stitched for added strength. This button-down shirt stores items securely in two chest pockets with flaps and button closures. Two-button adjustable cuffs help ensure a great fit. FR melamine buttons are used throughout.
