Smith lenses use only the highest quality Japanese polarized film for the truest color, object definition, and glare reduction. They combine it with both Techlite Glass and Carbonis Lens materials to give you the potions and optical performance you need to succeed. Building on the legendary success of Smith's Serpico aviator, they proudly introduce a scaled down, carbon copy. The Serpico Slim is identical in form and function to the original Serpico. Proportionally reduced in size and scale to accommodate smaller faces. Finally!
