Product Description Whether you're looking to sight your landing or simply take in the full mountain view, little compares to the widescreen view from inside a pair of Smith I/O goggles. Match the unobstructed view of their frameless design with our color-boosting, contrast-enhancing ChromaPop lens and the terrain just unfolds in front you as fast as you can take it all in. And don't worry about fogging. The I/O gets our highest level of anti-fog treatment and integrates with our helmets for airflow that keeps the view sharp through all weather conditions. The quick-release lens system lets you quickly match your tint to the day.
