There's no denying it: the Smith Shift MAG Sunglasses are fast. They've got speedy optics and crisp vision, encouraging PR's on the bike, the trails, and the skin track. In addition to the oversized, overstoked looks, they're also made with Smith MAG™ interchangeable lens technology, so you can rock the ChromoPop color-enhancing lens all day and easily swap out for the included clear lens when the sun goes down.
