The double-bridge support between the lenses on these cool sunglasses for men by BeOne gives the frame strength and looks cool at the same time. The frame is made of metal, flexible but strong enough to wear during whatever activity you choose. The arms are straight and squared off with the BeOne logo faintly seen on the side and a plastic coating over the curved earpieces. The lenses are dark and polarized, specifically designed to protect your eyes from the sun.
