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. Smith's ChromaPop™ lens tech boosts color and contrast, so every wind lip, landing, and tree glade is as sharp as possible. It gets the highest level of anti-fog treatment and integrates with Smith 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 Smith's quick-swap MAG™ lens system. Compatible only with lenses from 20/21 production season. Not compatible with lenses 19/20 or earlier.
