Our Take

We’ve tested dozens of goggles in whiteouts, wind, and high-altitude glare—this is the one that always makes the cut. The I/O MAG’s magnetic swap saves precious seconds when weather flips, and its fog control actually keeps up with the climb. The optics are crisp enough to spot crevasse texture before sunrise and the fit locks in perfectly under a helmet. When we’re guiding alpine routes, this is the goggle that earns a permanent spot in the kit.

Why We Love It
George Hedreen

When our guides are guiding in variable mountain light, they need gear that reacts as fast as the condition changes. The I/O MAG lets them change lenses with gloves on and stay focused on the route, not the gear. The ChromaPop™ lens reveals definition in flat light and the airflow keeps it clear even when they're breathing hard on the approach. It’s their go-to because it’s simple, fast, and never lets vision be the weak point.

“The smith I/O mag is optimal for alpine climbing due to its ease of swapping out lenses to accommodate a wide range of light conditions.”
— George Hedreen, RMI Guide

Our Philosophy

We Simplify Outfitting

Whittaker Mountaineering was born out of the need for RMI to make sure their clients had the appropriate gear to get to the top of Mt. Rainier safely. After decades of trying, reviewing, arguing-over, and recommending gear, we can’t help but know what we’re doing by this point. We know what works, we know what doesn’t, and we use that expertise to stock our store.
