DC Route FAQ

The Disappointment Cleaver route blends endurance, glacier travel, and mountain weather into one of America’s most classic climbs. Having the right system — from boots to layers — is key to comfort and success. Here are answers to a few common gear questions from our guides.

Should I use single or double boots on Rainier?

In summer, most climbers use single mountaineering boots for a lighter, more flexible feel. When freezing levels drop below 10,000 feet or the forecast calls for extended exposure, double boots are the safer and warmer choice. Always check conditions with your guides before deciding.

How should I layer for the Four or Five Day Climb?

You’ll need a full layering system: a moisture-wicking baselayer, a lightweight fleece or softshell midlayer, an insulated puffy, and a waterproof shell. Proper layering helps regulate temperature through changing conditions. See our Guide to Mountain Layering for detailed examples and recommendations.

I don’t see a tent in this collection — do I need one?

It depends on how you’re climbing. If you’re joining a guide service like RMI, you’ll stay in bunks inside one of the huts at Camp Muir, so no tent is required. Independent climbers, however, must bring their own tent and camp on the snow at Muir.
