You can only scope your line if you can see where you're going. Smith's ChromaPop™ lens tech boosts color 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 I/O MAG™ S is scaled down to fit smaller faces.
