Our Guides Choose This Goggle Glacier Glasses might come to mind before goggles in terms of mountaineering, but when there are 70 mph winds howling and your contacts are frozen in your eyes, we're pretty sure you'll be thinking of goggles; specifically the I/O Goggles from Smith. 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.
