The Smith 4D MAG S is the small fit version of the 4D MAG snow goggle, with the same magnetic lens change and downward curving lens. This one comes with a ChromaPop Sun Green Mirror lens installed and a second ChromaPop lens for low light.

What it's for

Skiing and snowboarding for riders with smaller faces who want the wide view of the 4D MAG. You get a dark mirrored lens for bright days and a second lens for storm days and flat light.

How it works

BirdsEye Vision: The bottom of the lens curves down and in toward your face. Smith says this increases the overall field of view by 25%.

MAG lens change: Magnets hold the lens to the frame, so you can swap lenses quickly when the light changes.

ChromaPop: Smith's lens tint technology. It filters light at the two points where blue and green, and green and red, wavelengths overlap, which gives greater definition and more natural color.

AirEvac ventilation: Vents in the goggle line up with the vents in Smith helmets to move warm, moist air out and keep the lens from fogging.

VLT: Visible light transmission is the share of light that reaches your eyes through the lens. Low numbers suit bright sun and high numbers suit clouds and flat light.
