X-Loop has come up with a unique design that is for active men who want something comfortable to wear to protect their eyes while they're playing sports or just enjoying the great outdoors. The frame is made of strong plastic, rigid and tough and also molded to fit comfortably and lightly. The arms taper straight back to the ear and feature the X-Loop logo on the side in raised silver letters. The lenses are large and offer excellent ultraviolet protection.
