Relwen blends their rugged Midwestern roots with an obsessive attention to detail, and it shows in pieces like the Flyweight Flex Shorts. They're made from a breathable and durable cotton blend with a small percentage of spandex for just enough stretch. Added features like a gusseted crotch panel inspired by old-school mountaineering shorts, and a shaped waistband that sits on the hips (and never restricts) maximize the comfort of these shorts. A snap-button waistband and black oxidized zipper are used to toughen the shorts while making them easy to wear for long days at a time.
