The 10 Best Mummy Bags

This wiki has been updated 14 times since it was first published in September of 2020. Unlike traditional rectangular models, mummy sleeping bags are more form-fitting, leaving less empty space between you and the shell, which results in better heat retention. They pack down tightly into compression sacks, and are also very lightweight, due to their down- or fiber-filled construction, making them ideal for camping, backpacking, or hiking expeditions in most climates. When users buy our independently chosen editorial choices, we may earn commissions to help fund the Wiki.

Editor's Notes

September 09, 2020:

When choosing a mummy sleeping bag, it is important to consider the environments in which it will be used, prior to purchasing. If it will be used for camping in the warmer summer months, then any three-season bag should be more than sufficient to keep you comfortable while you sleep. If, however, you will be using your bag in cooler climes, higher altitudes, and later in the year, then a bag with a high fill power and a low limit rating would be an essential part of your equipment.

Of the items in this ranking, the Coleman North Rim, Cascade Mountain Tech Adventure, Columbia Mount Tabor, Teton Sports Leef, and Hyke & Byke Katahdin, are all good examples of sleeping bags that are fit for purpose in milder conditions, and are suitable for use in most North American and European destinations during the spring to fall months.

If you intend to use your sleeping bag in cooler conditions, or need a good year-round solution, then the Kelty Tuck Synthetic, Hewolf Ultralight, Ubon Extreme, and Sierra Designs Nitro, are all worthy solutions, with the latter three being filled with high fill power down that is both very lightweight, extremely warm, and easy to dry when wet. While this is undoubtedly the best option for sleeping bag filler, this quality is reflected in their considerably higher prices.

One noteworthy model is the Geertop Ultralight, which is another duck-down filled bag that attaches to any hammock and incorporates a padded underside, making it ideal for sleeping alfresco, or inside larger tents. All the bags in this ranking come with built-for-purpose stuff sacks, which can be compressed to make space when traveling, and relaxed for storage, to ensure that the down or fibers within the bags are not damaged when left for long periods.

It is important to bear in mind the difference between comfort and limit ratings when selecting a sleeping bag. For example, if you see that a bag is rated at -15 degrees Fahrenheit, then this is its "limit" rating and it means that it will most likely keep you alive at this temperature. However, its "comfort" rating might be as much as 40 degrees Fahrenheit higher, so it's important to take both of these into account for both your safety and your peace of mind when sleeping outdoors.
