Smith I/O MAG Snow Goggle
I/O MAG family · 26/27
Technology
ChromaPop Lens
A contrast tint that filters two wavelengths of light known to cause color confusion, so terrain, texture, and edges read more clearly. It is a contrast tint, not a medical or corrective lens.
Spherical Carbonic-x Lens
A lens that curves both horizontally and vertically for a wide, low-distortion field of view, molded in impact- and scratch-resistant Carbonic-x.
SMITH MAG Lens Change
Magnets pull the lens into place and locking levers on each side hold it there, so swapping tints for changing light takes seconds without prying at the frame.
Smith’s highest-level anti-fog inner coating, designed to work with the airflow of Smith helmets to keep the view clear across changing weather.

- ·Offered in standard, XL, S, and Low Bridge Fit shapes
The Smith I/O MAG sits at the center of Smith’s MAG goggle line: a spherical goggle that pairs ChromaPop contrast optics with the fast MAG lens-change system. The spherical Carbonic-x lens curves in both directions for a wide, low-distortion view, and ChromaPop filters specific wavelengths of light to lift contrast and separate detail in the flat, variable light the Pacific Northwest serves up.
The MAG system is the reason to buy this tier: magnets align the lens and locking levers on each side hold it, so changing tints as clouds roll in takes seconds. The I/O MAG ships with two ChromaPop lenses — one bright-light tint and one low-light tint — so a single purchase covers most conditions. A 5X anti-fog inner lens, Responsive Fit frame, QuickFit strap with a clip buckle, and three-layer DriWix face foam round out the build, and the goggle integrates with Smith helmets for venting.
Fit is where the I/O MAG earns its range: it comes in a standard size, an XL, a smaller S, and a Low Bridge Fit for lower nose bridges or higher cheekbones. If you want more downward vision, the step-up 4D MAG adds a BirdsEye lens that curves down toward the face; the I/O MAG keeps a standard spherical shape. Reach for the I/O MAG if you want ChromaPop optics, two included lenses, and a proven fit range. Skip it if you need the extra downward field the 4D MAG provides, or if you never plan to swap lenses.
Safety — read this
ChromaPop is a contrast tint that helps you read terrain in flat light — it does not prevent injury or replace careful skiing. The lens is impact- and scratch-resistant Carbonic-x and blocks 100% of UVA and UVB, but a goggle is eyewear, not a guarantee against eye injury.
