SMITH 4D MAG XL Snow Goggles, Black, ChromaPop Sun Blue Mirror, X-Large — MAG lens-change, OTG fit

SMITH 4D MAG XL are oversized snow goggles with a 25% wider field of view, ChromaPop optics and a magnetic MAG lens-change system for fast, fog-resistant vision in variable light.

Built for larger faces and riders who demand the clearest read on the mountain, the 4D MAG XL pairs a curved lower lens profile and spherical optics to expand peripheral vision while keeping distortion to a minimum. The kit includes a Sun Black ChromaPop mirrored lens (S3) for bright conditions and an extra low-light ChromaPop lens (S1). Robust venting, triple-layer foam and 5X anti-fog protection help keep the view clear as you push speed or transition between tree runs and open faces.

How do these goggles improve what I see on the hill?

The spherical lens geometry and BirdsEye Vision shaping increase usable sightlines especially downward and to the sides, giving a 25% broader visual sweep than many conventional frames. ChromaPop enhances color contrast so edges, bumps and ice become easier to detect.

• Spherical lens for minimal optical distortion and true color.
• ChromaPop technology boosts contrast and natural color definition.
• Curved lower lens edge opens up more downhill and peripheral view.

How fast and reliable is the MAG lens-change system?

The MAG system uses seven weather-resistant magnets plus a mechanical double-lock to securely seat lenses while enabling rapid swaps. Two side levers release the lens, making mid-run changes easy when light shifts or you move between sun and shade.

• Seven magnets guide the lens into perfect alignment automatically.
• Dual side levers allow one-handed removal and installation.
• Patented mechanical locks keep the lens fixed during aggressive riding.

Will these fit with prescription glasses or larger helmets?

The 4D MAG XL is over-the-glasses (OTG) compatible and designed to integrate with Smith helmets for balanced fit and optimal venting. Wide strap, silicone backing and QuickFit adjustments keep the goggles secure even with thicker helmet liners.

• OTG-friendly frame spacing accommodates many spectacle frames.
• Ultra-wide, silicone-backed strap resists slipping on helmet shells.
• QuickFit slider lets you dial the strap length quickly on the slope.

What materials and anti-fog features keep the lens clear?

Optical layers combine a polycarbonate outer lens and cellulose propionate inner lens with a 5X anti-fog treatment. The frame uses TPU and molded nylon components for durable venting while foam layers and channeling reduce moisture buildup near the face.

• 5X fog protection coating on the inner lens for extended clarity.
• PU/PE blended foam for comfort and moisture management.
• TPU and nylon construction for structured venting and strength.

Who is this for: Riders with larger faces or anyone who wants maximum peripheral vision and quick lens swaps on-the-go. The SMITH 4D MAG XL suits alpine skiers, snowboarders and backcountry riders who need premium optics, reliable anti-fog performance and an OTG-capable, helmet-friendly fit. Choose the ChromaPop Sun Blue Mirror lens for bright, glare-prone days and swap to the included low-light lens when clouds or late-afternoon shade reduce contrast.
