Smith Optics Shift MAG ChromaPop Black Matte/Cinder Shield w/ Bonus Lens

Geared for speed, the Shift MAG from Smith Optics gives cyclists and runners every performance advantage possible, from the superlight frame down to the nose piece. The coolest feature is no doubt the interchangeable lens technology. Snap the magnet on the side for quick, fingerprint-free lens changes. Includes one clear lens as well a color-enhancing ChromaPop lens that provides 100% UV protection. Flatter than most performance eyewear, the 5-base frames stay put with a two-position nose piece and no-slip temples giving a secure feel when you're going your fastest.
