Smith Optics 4D Mag Goggle

The 4D Mag system uses magnets to guide the lens into place, allowing you to swap lenses in seconds without taking your gloves off. It is secure enough to handle hard impacts while making it incredibly easy to adapt to changing light conditions on the fly.

Yes, these are designed as Over-the-Glasses (OTG) compatible. The oversized frame provides enough internal volume to accommodate most standard prescription eyewear without pressing against your face.

BirdsEye Vision extends the lens curvature below the standard frame line, significantly increasing your downward peripheral field of view. This helps you see more of the terrain directly beneath you and around your feet, which is particularly useful when navigating technical or steep sections.

The 4D Mag features Smith's AirEvac ventilation system, which integrates with your helmet to pull warm, moist air away from the lens. Combined with the 5X anti-fog inner lens coating, they are highly resistant to fogging even when you are working up a sweat.

While they are optimized for Smith helmets to ensure seamless airflow, the strap design and frame shape are compatible with most major helmet brands. The silicone-backed strap helps keep them securely in place regardless of your helmet's specific shell shape.

ChromaPop lenses filter specific light wavelengths to enhance color definition and contrast. This makes it much easier to distinguish textures in the snow, such as ice patches or moguls, giving you better depth perception in varying light.
