Not your dad's windowpane-check dress shirt. New fabric alert: this is a new flannel for us and it took us a while to nail it, because we wanted one that was really warm, really soft, but also really durable and one that wouldn't pill. Well: check, check, and check. Colin is 6'1", wears a Medium, and in case you were jealous about how nice he looks in our tees....just know he puts them on in a really weird way. Sorry Colin, you know it's true.
