Upgrade your eyewear with Ray-Ban RB8319CH sunglasses. Sporty styling and chic details come together for a versatile, fashionable pair of shades. The metal frames of these Ray-Ban sunglasses feature carbon fiber temples. Carbon fiber is flexible and comfortable, and just as reliable as metal. The materials are also corrosion-resistant, so your shades can stand up to the elements. The emphasis on lightweight design creates a "barely there" feel. Textured temples and shark-fin details add subtle styling. These rectangular frames complement wearers with round or oval faces.
