Description

The Smith I/O MAG is a MAG-series spherical snow goggle built around Smith's ChromaPop lens technology, which filters specific wavelengths of light to sharpen contrast and separate detail in flat and variable light. Its spherical lens shape wraps horizontally and vertically to open up peripheral vision and cut the distortion a flatter lens can leave at the edges, and a 5X anti-fog inner coating paired with Smith helmet integration works to keep the field clear as the weather turns.

The I/O MAG suits all-mountain and resort skiers who want one versatile daily goggle plus the freedom to match the lens to the light. Its MAG interchangeable system uses magnets and locking levers, so a lens change takes seconds, and the goggle arrives with two ChromaPop lenses — one bright-light tint and one low-light tint — covering bluebird mornings through storm-day afternoons. A Responsive Fit frame, QuickFit strap, and three-layer DriWix face foam handle comfort and moisture. This is the standard I/O MAG frame with a Low Bridge Fit version for lower nose bridges or higher cheekbones; Smith also makes it in a larger XL and a smaller S, sold separately.

At PTO we fit the goggle to your face and helmet in the shop, walk you through the MAG lens swap, and help you choose tints for Pacific Northwest light before you ride.

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.

5X Anti-Fog & Helmet Integration

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.

Features

  • ·Spherical ChromaPop lens for contrast in flat, variable light
  • ·MAG magnetic plus locking-lever lens changes in seconds
  • ·Ships with two lenses — bright-light and low-light ChromaPop tints
  • ·5X anti-fog inner lens, the highest level Smith offers
  • ·Responsive Fit frame with three-layer DriWix face foam
  • ·QuickFit strap with clip buckle and silicone-backed webbing
  • ·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.

Strengths

  • +Spherical ChromaPop lens lifts contrast in flat light
  • +MAG magnets and locking levers swap lenses in seconds
  • +Ships with two lenses — bright and low light
  • +Wide fit range: standard, XL, S, and Low Bridge

Best For

All-mountain and resort skiers who want ChromaPop contrast, quick MAG lens swaps, and a fit that matches their face.

Limitations

  • −Standard spherical shape lacks the 4D MAG downward view
  • −Value depends on actually swapping lenses
  • −Premium tier pricing within Smith’s goggle line

Not For

Skiers who want the extra downward vision of the 4D MAG’s BirdsEye lens, or who never plan to change tints and would rather spend less.

A standard size, a larger XL, a smaller S, and a Low Bridge Fit shaped for lower nose bridges or higher cheekbones.
