Smith I/O Mag Goggles

It is very straightforward. The magnetic system allows you to pop the lens off and snap a new one in place in seconds, even while wearing gloves, making it easy to adapt to changing light conditions on the chairlift.

Yes, the I/O Mag XL is designed to be OTG (Over-The-Glasses) compatible. The large frame provides enough interior volume to accommodate most standard prescription eyewear comfortably.

The spherical lens mimics the curvature of the human eye, which helps eliminate optical distortion and provides a wider, more natural field of view compared to flat, cylindrical lenses.

The I/O Mag XL features an advanced anti-fog coating and integrated ventilation channels designed to promote airflow. While no goggle is entirely immune to fogging in extreme conditions, this system is highly effective at keeping your vision clear throughout the day.

They are designed for seamless integration with Smith helmets, but the large frame shape is generally compatible with most major helmet brands. The silicone-backed strap also helps keep the goggles securely in place regardless of your helmet's specific design.

The package includes two lenses: a photochromic lens that automatically adjusts to variable light conditions and a dedicated low-light lens for stormy or flat-light days.
