Mountain Logic™

Gear info and tips from some of the most experienced mountain guides on the planet.

Gear selected by guides.

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.

Reviews We're Proud Of

I have been a customer of Whittaker Mountaineering for decades. This is the place I shop for technical and recreational outdoor gear. Customer service and expertise are beyond belief! I always get the right gear for the right application. They hit it out of the park every time...BRAVO!

Daniel Rogers

I came across Whittaker Mountaineering last July when visiting the park. Staff was excellent in both the gear rental area and the shop. Knowledgeable, attentive, and friendly. I purchased a jacket this fall and I was notified it was out of stock. Staff went out of their way to recheck inventory and found jacket in a different color. Very impressed. Jacket and other purchases were perfect fit and quality. I am a big fan of this place.

Tess Buescher

I'm an adventure expert and have used Whittaker for years. Renewing my equipment after excessive use will only be Whittaker-bought. They will never oversell expensive gear, but you get equipped for your needs.
