Mountain Logicâ„¢

We Simplify Outfitting

Climbing is our bloodline, since Jim and Lou Whittaker led first American ascents worldwide. Lou's son and Rainier Mountaineering Inc. co-owner/senior mountain guide Peter Whittaker built Whittaker Mountaineering to make outfitting more efficient: The world's best mountain guides pick only the gear you need, nothing you don't.
