These semi-rimless sports sunglasses are made for active men by X-Loop and feature a tough style and build that will keep you safe and keep you looking good at the same time. The frame is made of plastic with a rounded interior curve that lets the glasses fit snugly and stay on no matter what you're doing. The arms start thick and have several texture elements that add grip and strength. The X-Loop logo is on the side, and the lenses have a dark finish that blocks the sun.
