The Ruckus Chromapop Sunglasses are Smith's premiere performance sunnies, and we love them for cycling, running, and working out under the bright sun. Smith's most innovative lens technology, Chromapop enhances overall clarity by filtering out secondary colors to make natural colors really pop. The Ruckus also has a unique frame that lets us switch out lenses easily, and the included bonus lens shows us the difference right out of the box.
