The Kai contemporizes the look of a traditional square frame by making it Crystal Grey and adding fresh Blue Mirror lenses. Made of shatter-resistant, lightweight polycarbonate, the frames feature premium metal hinges, and they are molded around the ears to provide a comfortable fit. The lenses provide UV400 protection from the harmful rays of the sun, plus they are polarized to block glare from reflective surfaces. These unisex sunglasses complement a variety of facial shapes, and they fit virtually all faces from small to large. A cleaning cloth microfiber pouch is included with each pair, so you can easily keep your new sunnies clean and safely tucked away when not in use.
