When you think of Air Force brand and aviator sunglasses, a uniform shape usually comes to mind. These cool shades for men are anything but uniform with their textures and a low-profile shape. The frame is made of metal, and the arms are plastic, made to flex and bend to hold shape but also durable and rigid as needed. The arms are straight and thin with an outer texture that adds to grip. The lenses are dark and round and set between a double-bridge structure.
