The Los Angeles is the most popular GOWOOD style. The temples are made of real walnut wood. The front is made of 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. Our 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.
