Lens Flat light. Blowing snow. Sunshine. Every day on the mountain brings different conditions. The Smith Rally goggles keep everything in view and seal out the elements no matter what the weather does. Their slim, modern frame and wide cylindrical lens maximize your view. Smith's Airflow lens technology provides active ventilation for fog-free visibility through the best and worst conditions. The design offers a smaller, low-profile fit for a wide range of faces and full helmet compatibility.
