The Smith Men's Ruckus Performance Sunglasses are the epitome of eyewear technology. These sunglasses are built with re-engineered PivLock(TM) lens change technology, thin megol temples for helmet compatibility and no-slip comfort for the longest road rides and gnarliest trails. The Ruckus feature a raised brow design that increases peripheral vision in the riding position, and top bar venting and two-position nose pads that provide proper fit to help minimize fogging and maximize comfort. Equipped with 2 interchangeable ChromaPop(TM) lenses for bright sun and low light, you can ride in all conditions.
