Whether you're dropping in on a hike-to line or charging through a storm day at the resort, the Smith 4D XL goggles set you up with the best field of view possible. They combine the unmatched peripheral range of our BirdsEye VisionT lens with an oversize XL frame and the terrain boosting optics of ChromaPopT, so you don't miss a wind lip or terrain change. Our MAG lens-change tech lets you swap lenses to match the light conditions with ease. Their XL size makes them the only OTG compatible goggles in our 4D lineup. Buckle up and embrace the fall line with confidence. Fine-tune your kit with additional or replacement goggle lenses for sunny conditions, variable conditions, and cloudy conditions.
