Smith Optics Leadout Pivlock Sunglasses in Frame Color Matte Black. Chromapop Black Lens (VLT 10%). Comes with a ChromaPop™ low-light amber lens for overcast conditions, two different sets of Megol nose pads (a high- and low-bridge) and a hard case with a microfleece storage bag. 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.
