Smith Optics 4D Goggles

The 'S' indicates that this is the smaller version of the standard 4D MAG goggle. It is specifically designed to provide a better, more secure fit for skiers and snowboarders with smaller face shapes.

BirdsEye Vision curves the bottom edge of the lens downward, extending your field of vision below your peripheral line. This allows you to see more of the terrain directly beneath your feet without having to tilt your head down, which is helpful when navigating steep or technical lines.

Yes, the Smith MAG system uses magnets to guide the lens into place, making it very intuitive. While it is easier to swap lenses with bare hands, the magnetic snap-in design is simple enough to manage with thin gloves or mittens on the chairlift.

While these goggles are optimized for seamless integration with Smith helmets—specifically utilizing the AirEvac ventilation system to prevent fogging—they are compatible with most major helmet brands. However, you may experience a slight gap or less efficient airflow depending on the shape of your helmet's brim.

Low Bridge Fit is designed for people with a lower nose bridge or a wider or higher cheekbone structure. It adds extra face foam in the nose area to ensure a proper seal, preventing light leaks and cold air from entering the goggle.

Most 4D MAG S packages include two lenses: one for bright, sunny conditions and a secondary ChromaPop lens specifically designed for low-light or stormy days. Check the specific product listing to confirm which lens tints are included in your box.
