Sleeping Bag Ratings >>
Sleeping Bag Temperature Rating Accuracy -- Based on Data From Over 1,350 Actual Owners
Temperature ratings for sleeping bags refer to the temperature it can be outdoors before the bag is unable to keep you warm. For example, a sleeping bag with a 30 degree Fahrenheit rating is designed to keep the average person warm down to 30 degrees.
Based on owner data, however, these ratings are often inaccurate in that they overestimate the warmth of the sleeping bag by an average of about 15 degrees. This means that if you want to stay warm down to 30 degrees F, then you should probably buy a sleeping bag with a temperature rating of 15 degrees F or lower.
Remember that it is far wiser to have a sleeping bag with too much warmth than not enough.
The chart below shows how the various brands rate in regard to temperature rating accuracy based on actual owner data. Keep in mind that the chart below represents what is often, but not always, the case; a particular model may go against these findings.
