Flannel is a great feeling. And canvas is tough as nails. We put the two concepts together. The Carhartt 100590BT 9-ounce, 100% cotton-washed canvas shirt jac features 4-ounce, 100% cotton flannel lining and is garment washed at the factory for a comfortable, soft finish. There are antique-finish brass snaps throughout, two durable chest pockets with rivet reinforcements, an interior pocket, and a bi-swing back for better range of movement. The two-button adjustable cuffs with extended plackets enhance comfort and convenience. Built Carhartt-tough with triple-stitched main seams.
