Sports sunglasses should be durable and also look cool, and these sweet shades for men by X-Loop do both and more. The frame is made of strong plastic and is molded to fit your head snugly. The arms feature subtle design elements and curve slightly down to the ear. The X-Loop logo is displayed in silver letters on the side of the arms. The lenses are dark and polarized for maximum protection from the sun and glare elimination. The lenses are set in the frame in a semi-rimless style.
