AI FAQs
AI generated FAQs about the 4D Mag XL
Will these goggles fit my face shape?
These goggles have a medium/large fit, a Standard Bridge Fit, and an oversize XL frame. That fit profile is designed for riders who suit a medium-to-large goggle footprint.
How do I know if the strap will stay put while I'm moving?
The ultra-wide strap has silicone backing to help it stay put while you move. QuickFit adjustment lets you dial in the fit quickly before dropping in or heading out on a tour.
Do these goggles fog up easily?
A 5X anti-fog inner lens, three-layer DriWix face foam, and AirEvac ventilation are built in for fog-free performance. The ventilation system is designed to integrate with Smith helmets for clearer lenses during active skiing and riding.
Can I wear these over prescription glasses?
The 4D Mag XL is over-the-glasses (OTG) compatible. Its XL size makes it the only OTG-compatible goggle in the 4D lineup.
How do I adjust these for a snug fit?
Use the QuickFit strap adjustment system to set the fit quickly. The ultra-wide, silicone-backed strap helps maintain that adjustment while you ski or ride.
Will I need different lenses for different times of day?
These goggles include two lenses, and the MAG magnetic system makes lens changes quick and easy. You can swap between the included lenses to match changing light conditions through the day.
Can I see my surroundings clearly with these on?
BirdsEye Vision is designed to expand peripheral visibility so you can better see riders and terrain at the edges of your view. The spherical ChromaPop lens also enhances contrast and natural color for clearer terrain detail.
Are these suitable for both on-slope and off-slope use?
These goggles are built for both resort storm days and hike-to lines. Their terrain-detailing optics and wide peripheral view support skiing and riding where terrain changes and nearby riders matter.
Can I swap the lenses on these goggles?
The Smith MAG lens-change system uses magnets for quick, easy lens swaps. Two lenses are included so you can change lenses to suit the light conditions.
What comes in the box with these goggles?
The package includes the goggles, two lenses, a goggle hardcase, and a microfiber goggle bag with a replacement-lens sleeve. The second lens and protective storage pieces support changing conditions and organized transport.
