Product Details

The 4D MAG gives you a broader view of the slope, including the riders and terrain just outside your usual line of sight. Smith’s BirdsEye Vision increases the field of view by 25%, while ChromaPop lenses bring more contrast and natural colour to changing mountain detail. The result is a clearer read on the snow without making the goggle feel complicated. It has a standard fit and includes a bright-light lens plus a low-light lens, so you can adjust your setup as conditions shift.

Changing lenses is straightforward: the Smith MAG system uses magnets to make swaps quick and easy. A three-layer DriWix face foam manages moisture, while AirEvac ventilation works with Smith helmets to support fog-free lenses. The QuickFit strap adjusts quickly, and its ultra-wide silicone backing helps keep the goggle in place. The package includes a hardcase and microfiber goggle bag with a replacement lens sleeve. A Low Bridge Fit is also available for faces with a lower nose bridge or wider, higher cheekbones.
