The Smith Shift MAG Sunglasses are geared for speed. The ShiftMAG™ 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. These Smith sunglasses come with one clear lens as well as a colour-enhancing ChromaPop™ lens. Flatter than most performance eyewear, the 5-base frames stay put with a two-position nose piece and no-slip temples. They give you a secure feeling when you're going your fastest.Smith Shift MAG Sunglasses FeaturesChromaPop™ lenses enhance contrast and natural colour to make the details popMedium fit, large coverage5-base lens curvature for slight wrap fitMegol temples provide a non-slip grip, so glasses stay putTwo-click position adjustable fit Megol nose padsSmith MAG™ lets you change lenses quicklyIncludes: Clear lens,Performance hard case,Microfiber bag More info
