Abacos Kai contemporizes the look of a traditional square frame by making it Rubber Tortoise and adding fresh Brown 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. All Abaco Sunglasses are Guaranteed to be 100% Authentic and in New Condition, and an Abaco 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.
