Welcome to our Back Yard

Mount Rainier is the most heavily glaciated peak in the lower 48 and where the Whittaker name became synonymous with American climbing. After 20+ years of outfitting climbers on Rainier, we can't help but know what works best.

We've worked with the guides at RMI Expeditions to curate a gear list specifically for your 4 or 5-day climb of Rainier - no frills and only the best choices. For more info, check out RMI's Rainier Gear List.
