When we designed the classic Riptide sunglasses, we left no stone unturned. These Smith biodegradable frame sunglasses combine a classic look with Italian craftsmanship. Spring hinges provide added flexibility at the temples, providing a more comfortable and secure fit that’s great for running or riding. These Italian sunglasses are available with ChromaPop+ polarized lenses that enhance detail, color, and clarity while reducing glare, or ChromaPop Glass lenses that are also more scratch resistant.
