Put it into high gear with the Smith Shift Split MAG™ sunglasses. Their split-frame design provides an obstruction-free view of the road and trail with a lightweight feel that stays put through technical trails and full-gas descents. With ChromaPop™ lens tech, they ensure crisp visuals to keep you on track and charging. Interchangeable lenses let you choose the right tint, and the Smith MAG™ system makes for quick, fingerprint-free lens changes thanks to its simple magnetic-clip design.
