The Smith 4D MAG Low Bridge Fit is the goggle for riders who want the most unobstructed view the mountain has to offer. The spherical lens uses Smith's BirdsEye Vision design — the bottom of the lens curves inward rather than stopping at the frame, which opens up your downslope and peripheral vision in a way a flat bottom frame simply can't. ChromaPop optics sharpen color and contrast across light conditions, and the goggle ships with two lenses: one ChromaPop lens tuned for bright light and a bonus ChromaPop lens for low-light or overcast days. Swapping between them takes seconds with the MAG magnetic system, which clicks into dual outrigger locks on the frame so the lens stays exactly where it should under a hard fall.
The Low Bridge Fit is specifically cut for faces with a lower nose bridge or wider, higher cheekbones — if standard goggles gap or shift around on your face, this frame addresses that. Frame size is medium. It integrates with Smith helmets through the AirEvac ventilation channel, which helps keep air moving and the inner lens fog-free. Three-layer DriWix foam handles moisture on the inside, and the 5X anti-fog treatment on the inner lens backs that up. One thing to know: this goggle is not OTG compatible — if you wear glasses on the hill, look at the 4D MAG XL instead, which is the only 4D variant with glasses clearance. UV coverage is 100% UVA/UVB.
