Product Details

The 4D MAG S brings Smith’s broad BirdsEye Vision to smaller faces, expanding the field of view by 25% so the line ahead and movement at the edges stay easier to read. ChromaPop lenses enhance colour, contrast, and definition without making the view feel busy. The result is crisp, natural-looking terrain detail when you are checking snow texture, a landing, or the riders around you.

Lens changes are quick thanks to the Smith MAG magnetic system, and the package includes a bright-light lens plus a low-light option. Three-layer DriWix face foam manages moisture, while AirEvac ventilation is designed to work with Smith helmets. A silicone-backed strap and QuickFit adjustment help keep the fit settled through a full day on snow.
