X-Loop makes a mean pair of men’s aviator sunglasses that look cool and tough and still feature a classic shape. The frame is made of metal, and the arms are made of plastic, a combination that lends durability to the lightweight construction. The arms are straight with a squared-off look, and they sport the X-Loop logo on the side. The lenses have an either mirrored or smoke finish that looks great while protecting your eyes and gives you added privacy. Buy in bulk for excellent savings.
