Aviator sunglasses look cool, and these shades for men and women by Khan look especially cool. They feature a gradient-smoke lens that adds an element of mystery to the wearer and provides privacy and protection from the sun. The frame is made of metal, and the arms are plastic, so the glasses flex and mold to your face, but are strong and rugged when they need to be. The arms sport the Khan logo on the side. Purchase the assortment in bulk for a nice discount.
