Features
You can only scope your line if you can see where you're going. Putting on the Smith I/O MAG XL goggles is like flipping the switch from regular to extra-widescreen. Our [Smith's] ChromaPop™ lens tech boosts color and contrast, so you get the clearest picture of the terrain ahead. Our highest level of anti-fog treatment and air flow keep the view sharp. Whether the day dawns clear or stormy, lens swaps are a snap thanks to our quick-swap MAG lens system. Because no two faces are the same, the XL model expands on the standard size for those looking for the largest possible lens.

AI FAQs
AI generated FAQs about the I/O Mag XL
Will these goggles fit my face shape?
The I/O MAG XL has a large fit and a Responsive Fit frame that adjusts to your face for a precise, comfortable fit. Its XL design expands on the standard I/O MAG to fit more faces while providing Smith’s largest possible lens.
How do I know if the strap will stay put while I'm moving?
The ultra-wide strap has a silicone backing designed to stay put while you move. QuickFit adjustment lets you dial in the strap tension quickly for a secure on-snow fit.
Do these goggles fog up easily?
A 5X anti-fog inner lens, airflow, and moisture-wicking three-layer DriWix face foam are built to keep the view sharp. The goggle-to-helmet integration is also designed to support venting and fog-free performance during active days.
Can I wear these over prescription glasses?
These goggles fit over glasses and are compatible with Smith’s Optical Docking System prescription lens insert. That gives you two prescription-friendly setups: wearing your glasses underneath or using the compatible insert system.
How do I adjust these for a snug fit?
Use the QuickFit strap adjustment system to find your fit quickly. The Responsive Fit frame adjusts to your face, while the silicone-backed strap helps hold that fit in place.
Will I need different lenses for different times of day?
These goggles include two lenses and use the magnetic Smith MAG system for quick, easy lens changes. The setup is built for switching lenses as conditions move between clear and stormy weather.
Can I see my surroundings clearly with these on?
The spherical Carbonic-x lens delivers distortion-free optics, and ChromaPop enhances contrast and natural color. The XL design uses Smith’s largest possible lens for an extra-widescreen view of the terrain ahead.
How well do these protect against wind and UV?
These goggles provide 100% protection against UVA and UVB. The spherical Carbonic-x lens adds impact resistance while maintaining distortion-free optics.
How should I store these to keep them in good condition?
Store the goggles in the included microfiber goggle bag and use the replacement-lens sleeve for the extra lens. The included Smith x gogglesoc lens protector adds another layer of protection when the goggles are not in use.
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 your setup as weather and light shift.
