Sandstone Twill L/S Shirt by Carhartt. A micro-sanded and pre-washed finish makes our sandstone twill shirt extra comfortable and soft. Made of 8-ounce, 100% cotton it features a button-down collar, flap chest pockets with button closures and a back center box pleat for ease of movement. Main seams are triple-stitched for durability. For a slimmer fitted look we recommend going a size down from your normal size.
