Changing conditions on the mountain demand adaptability—and the Smith Squad MAG Goggle is designed to keep up. It pairs a semi-frameless cylindrical lens design with Smith’s MAG lens change system, combining six magnetic contact points with two locking levers for fast and secure swaps.  FEATURES: Spare lens included (bright light and low light ChromaPop lens) Magnetic lens changing system (Smith MAG Technology) ChromaPop lens technology enhances contrast and natural colour Cylindrical lens shape 5X anti-fog inner lens for advanced fog-free performance Medium fit GOGGLE CARE TIP:Fog happens—it's just part of riding in the mountains. To keep your goggles in top shape, never touch the inside of the lens; there's a super delicate anti-fog coating that can be damaged with even the lightest touch. Always store them in a soft bag, avoid placing them face-down, and let them air dry naturally after use. Steer clear of heaters or humid spots to keep them clear for your next run.
