Sports sunglasses need to be durable and have to protect your eyes, but they can also look cool as evidenced by these sweet shades for men by X-Loop. The frame is plastic, durable and strong to hold up to constant rough use, but with a lightweight construction that makes them comfortable and easy to wear. The arms have a cutout section in the middle with the X-Loop logo bridging the gap. The lenses are dark rounded rectangles with a protectant finish.
