Crafted from supersoft brushed twill (aka flannel's lighter-weight cousin), this shirt is cut to be more polished than a rugged, heavier workshirt. We use 3.48-ounce cotton twill and brush it so it feels like a featherweight flannel. If you look closely, you can recognize twill by its distinctive diagonal weave, a hallmark that adds both strength and flexibility to the fabric. Wear this easy button-up straight out of the dryer for an effortless, rumpled look or give it a quick iron for a more put-together appearance. It has all the versatility of our best-selling Secret Wash cotton poplin shirts, and it's ready to go under a blazer or over a vintage tee. 100% cotton. Machine wash.
