Sleeping bags today offer a lot of choices with various materials, weights, shapes, and temperature ratings. Unless you are an experienced backpacker, it may be a bit intimidating to evaluate all your options and get the right sleeping bag for you. When backpacking or camping in high altitude or even slightly chilly nighttime weather, a mummy bag will keep you warmer.
EN Temperature Ratings for Mummy Sleeping Bags The temperature rating on a mummy bag is the main factor which will indicate to you the warmth the mummy bag will provide. Most sleeping bag manufacturers use the EN temperature rating system, which indicates the lowest temp that you can expect your sleeping bag to keep the average camper warm at night. For example, if your mummy bag says it is rated for 30°, you should expect the average person would be comfortable if the temp got as low as 30°F, but they may not be warm at a temperature less than that. A good practice is to choose a bag with a rating of 25° less than what you expect the coldest weather to be. In spite of the direction these ratings can provide, the United States currently has no standard to measure these ratings and many variables can affect how warm a person will feel that just cannot be replicated in a testing lab. For example, a person with a high metabolism may not feel as chilled as someone else and most women sleep colder than men. Other factors include whether you are using a sleeping pad (highly recommended), the clothing you wear and the material of your mummy bag. Mummy Sleeping Bag Temp Ratings for Different Seasons You should always keep your regional climate in mind as the temperatures across the U.S. vary widely during the seasons. This is a rough seasonal guide to mummy bag temp ratings for the average person in average seasonal temps, all listed in °F:
