The views are half the fun of being out there. From trail riding to sunrise runs, the Smith Leadout PivLock makes lens changes quick and easy so you can adjust to varying light conditions while on the move. Designed with less wrap than most performance sunglasses, they allow air to circulate to reduce fogging. The lightweight frame is impact-resistant and integrates with Smith helmets. And to help you get more time outside, we threw in a set of ChromaPop™ low-light amber lenses ideal for flat light days and dawn patrol.Fine tune your kit with additional or replacement lenses for sunny conditions, variable conditions, and cloudy conditions.
