What is the best sleeping bag for climbing Mt. Rainier?

What type of mummy sleeping bag should I use for climbing and camping on Mount Rainier?

1 Answer


For climbing Mt. Rainier you'll typically want a down sleeping bag with a "comfort" rating between 0°F to 20°F, depending on the month of the year you are climbing. The typically climbing season for Mount Rainier is between May and September.  When it comes to sleeping bag brands, Feathered Friends, Western Mountaineering, and Mountain Hardwear make some of the most highly rated sleeping bags for camping and mountaineering.

If you're planning to climb Mt. Rainier in the spring or fall months of May, June or September a sleeping bag rated at least 0° Fahrenheit or lower should be used. A 0°F degree bag is one of the most versatile sleeping bags you can own. Here some sleeping bags to choose from:


If you're climbing Rainier in the warmer summer months of July and August then a slightly warmer bag may be used with a comfort rating of 10°F to 20°F.

The best sleeping bag to bring will, is determined by season, weather forcasted conditions and your own personal preferences (if you sleep hot or cold).  You often want a sleeping bag rated 15 degrees lower than the coldest temperature you expect to face on the mountain, to ensure you will have the proper warmth while sleeping. 

Make sure you also have a compression stuff sack such as the Sea to Summit eVent® Compression Dry Sack

We also highly recommend a Therm-a-Rest NeoAir XTherm Mattress.
