Smith 4D MAG XL Goggles
The Smith 4D MAG XL Goggles bring Smith's expansive BirdsEye Vision™ to a larger, OTG-compatible frame for riders who want maximum visibility and extra room. BirdsEye Vision™ delivers a 25% increase in overall field of view compared to the I/O MAG, while ChromaPop™ Lens Technology enhances contrast, natural color, and terrain definition. Smith MAG™ uses eight magnetic contact points with dual locking mechanisms for fast, secure lens changes, while 5X™ anti-fog technology and AirEvac™ ventilation help maintain clear vision. Two ChromaPop™ lenses—one for bright light and one for low light—are included for changing conditions throughout the day.
