We trust The North Face Inferno -40 because it is uncompromising in its design, stripping away unnecessary weight while doubling down on crucial thermal retention features. It is a dependable, expedition-proven sanctuary we rely on to help you recover and sleep soundly when the temperatures outside the tent drop to absolute extremes.

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.

Who are these guys?

The North Face

Since 1966, The North Face has been a driving force in outdoor exploration, building gear that inspires and enables athletes of all experience levels. We carry them because they consistently deliver an incredible balance between cutting-edge innovation and everyday reliability. Whether you are outfitting for your first rainy day hike in the Cascades or gearing up for a major high-altitude summit, The North Face provides thoughtfully engineered apparel and equipment that our team trusts to keep you protected in any environment.
