When precision matters, the Smith 4D MAG delivers a level of visual awareness that changes how you ride. Designed with Smith’s widest field of view, these goggles let you read terrain contours, spot subtle transitions, and track movement at the edges of your vision with confidence. ChromaPop™ lens technology sharpens contrast and color, helping snow textures and shadows stand out in all light conditions.
At the core is Smith’s MAG™ lens system, using secure magnets to make lens swaps fast and intuitive—no fumbling, no cold fingers. Seamless helmet integration and advanced ventilation keep airflow moving and fog at bay, so your vision stays clear whether you’re dropping into a steep line or lapping the resort from bell to bell.
