Called an overshirt, because it's a heavyweight button down that can be worn alone... or you know, over a shirt. See where we're headed here? Wear it as a jacket over a tee, or by itself. Ya can't go wrong. Brushed for softness for a peached, vintage look. We mixed cotton and wool together to create a warm, heavyweight fabric that's absurdly soft (and also won't pill). Brooks (lead vocalist turned Marine Layer model) is 6’0” and wears a Medium.
