Sleek and aerodynamic, these great shades for men are made by X-Loop and are designed for active use. The frame is made of metal, and the arms are plastic, lightweight and easy to wear, but also strong and durable to hold up under tough conditions. The arms have an inward curve that grips your head and keeps the shades fitted firmly. The X-Loop logo is seen on the side in silver and black. The lenses have a mirror finish that reflects UV rays and gives you excellent privacy. Purchase these single-color glasses in quantity of 12 pairs per box.
