A bold 100% bamboo frame with a matte black finish. Slightly angular, and accented with a hint of a stripe in signature Martone Cycling Co. red, with a touch of navy for contrast. These sunglasses feature the season’s signature rose gold-tinted, UV400 protected, scratch resistant polarized lenses. Steel hinges on the stems hyper extend so your sunnies always keep their shape. Effortless, light weight (they even float in water!) and totally original.
