You can only scope your line if you can see where you're going. Putting on the Smith I/O MAG™ goggles is like flipping the switch from regular to widescreen. Our ChromaPop™ lens tech boosts colour and contrast, so every wind lip, landing, and tree glade is as sharp as possible. It gets our highest level of anti-fog treatment and integrates with our helmets for airflow that keeps them fog-free through all weather conditions. Whether the day dawns clear or stormy, lens swaps are a snap thanks to our quick-swap MAG™ lens system. Because no two faces are the same, the XL model expands on the standard size for those looking for the largest possible lens.
