The Heron Flannel Shirt Men is made from a thick, lightly brushed organic cotton flannel. They are our regular fit, so a straight cut with pleats in the back for extra volume. The Heron Flannel Shirt has two bellowed chest pockets with flaps, a classic placket and imitation horn buttons. It also has a ‘butcher’s button’: a smart button on the upper sleeve and an extra buttonhole in the cuff so the sleeve can easily be turned up when needed.
