The TOASTER's lightweight, small fit frame and stylish design make it a leader in the Slider collection. Smith's patented Interchangeable lens system utilizes distortion-free 9 base Carbonic lenses in all Slider frames to provide precise optical clarity and maximize coverage while minimizing peripheral exposure to sun, wind, and glare. With over a dozen replacement lens tints to choose from, the Smith Slider series provides sunglass versatility across the full spectrum of light conditions and sport eyewear enhancements. As always the Toaster is backed by Smith's lifetime warranty.
