Don't choose convention to fit in. Blaze your own trail with Ray-Ban® Xan Bio-Based RB4431 Sunglasses. These ultra-modern, low-profile Ray-Ban sunglasses feature injected-nylon frames with a high bridge fit and straight browline that continues its lines to the tall temples. Those temples taper into a comfortable curve that lands behind the ear, creating a sleek appearance and blocking more peripheral light.
