Outdoor shirt crafted in sturdy organic cotton twill. We've added a light padding for extra warmth. The quilted twill lining is a mix of recycled polyester and organic cotton. With his deep blue navy shade and the contrasting lining in a beige shade that almost looks like gold, Glenn has an air of elegance around him. In a denim kind of way. When you buy this shirt, you can be sure that we have paid our share of living wages for it.
