This men's shirt jac is made from 7.6-ounce, 67% cotton/30% polyester/3% elastane stretch herringbone fabric with Rugged Flex technology that allows for greater range of motion. It has a relaxed fit cut closer to the body, a spread collar that lays flat, buttoned chest pockets with a built-in pencil slot, lower front pockets for storage, adjustable cuffs, a flat-bottom hem, and triple-stitched main seams for added toughness. Designed as a versatile mid-layer for work and everyday wear, it is available in colors including Carhartt Brown.
