The sophisticated shape and hardwood construction of the Shwood Florence Select Polarized Sunglasses combine to create a ruggedly elegant look. Rounded eyes and a keyhole bridge give it a classy, vintage look, while layered multi wood construction and metal temple caps add heritage inspired style. Birch core construction adds both flexibility and durability while reducing the amount of overall material used, resulting in thinner and lighter wood sunglasses. Premium Carl Zeiss lenses offer superior optics, and they're polarized to eliminate glare. A hand sewn leather case keeps your shades safe when you're not wearing them.
