Long runs, hot laps on the mountain bike or a fast-paced road ride, a clear view of the rocks, roots and terrain ahead is essential. You can count on the Smith Vert PivLock? sunglasses for a distraction-free feel and a widescreen view that lets you get in the zone whether you?re letting it rip downhill or measuring your effort on a climb. Their cylindrical shield lens and rimless design make for an ultralight, low-profile fit and unobstructed vision. The PivLock? design lets you easily swap between the ChromaPop? lens and the bonus clear lens to match the light conditions. Non-slip nose and temple pads keep the Vert right where you need them down high-speed descents and across rough terrain.
