New to the GOWOOD collection and already a real hit! The Kauai line is all about being trendy and stylish. The panto style round front frame is made of ultra clear / transparent acetate. Acetate is less likely to break and better for the environment. We use outward flexible metal hinges for a flexible and comfortable fit. All GOWOOD sunglasses provide real protection with their CE certified category 3 lenses. These pink mirrored lenses are made of ultra high quality CR39 (Resin) material, which provides a very clear view and keeps the mirrored coating on for years to come. They are impact-resistent and are provided with a hardwood bamboo storage box for protective purposes, as well as with a microfiber pouch to clean the lenses.
