Decoding Sleeping Bag Temperature Ratings
Before EN testing standards were widely adopted for sleeping bags, temperature ratings were assigned to sleeping bags by manufacturers based on their own standards and testing methods- which included anything from real-world testing to sleeping inside a meat locker. Because there was such great variation in the testing methods used by different brands, the ratings that were produced ranged from inflated to overly conservative. At best, these in-house ratings provided a very rough guide for choosing the best sleeping bag. It was also nearly impossible to compare sleeping bags reliably across different brands.
Fortunately, in recent years, the EN testing standard has been adopted by most of the major sleeping bag manufacturers. A third party conducts these tests in labs that are internationally certified and standard testing methods are used on every bag. The ratings that are product are therefore a good indication of what temperature range a particular sleeping bag will perform in the best. More importantly, having standardized testing makes it possible to compare sleeping brands reliably across various brands, which helps you choose the ideal bag to use on your next trip. Whenever you are reviewing EN temperature ratings, you will want to consider and look for two main numbers- the EN lower limit rating and EN comfort rating. The comfort rating on a sleeping bag is an indication of the lowest temperature that the average woman can comfortably sleep in the bag, while the lower limit rating is an indication of the lowest temperature that the average man can comfortably sleep in the sleeping bag.
-40 degree F to +4 degree Sleeping Bag
If any ice or snow will be involved in your camping or other adventure, then this is the category of sleeping bags that you will most likely want to choose from. Typically these sleeping bags offer draft eliminating features such as collars and zipper baffles, high fill value and down insulation. A sleeping bag with this temperature range is called for in activities such as winter camping trips, mountaineering expeditions and multi-day ski tours.
+5 degree F to +29 degree F Sleeping Bag
The bags that are included in this category are accurately described as three-season sleeping bags. Out of all of the categories, they provide the most versatility. Whether you want to embark on a car-camping adventure during the early spring, go on an alpine backpacking trip in the summer, or set out on a multiple day biking tour during the fall, you will want to choose your sleeping bag from this temperature range.
+30 degree F to +55 degree F Sleeping Bag
For summer camping and backpacking adventures in moderate or low elevations, a sleeping bag that is rated with this temperature range should be selected. Since these sleeping bags don’t need to have as many heat-saving features or as much insulation in order to achieve this temperature rating, typically they will weigh less than four- and three-season bags. This makes it easier to pack and carry these bags on backpacking excursions.
Other Factors That You Should Consider
There are several other factors you should consider besides weather that can affect what temperature rating has been assigned to a sleeping bag. For example, sleeping inside a bivy sack or tent adds approximately 10 degrees of added warmth to the bag’s assigned rating. How much clothing you are wearing of course will also affect how warm you are. As a reference point, the EN tests use heat-sensor mannequins that are wearing a hat and one long underwear layer. Your sleeping pad’s insulating value may also affect how warm you are. Many sleeping pads have an R-value assigned to them that indicates how well they can insulate you when you are lying on the cold ground. The higher an R-value is, the better. Whenever you are selecting a sleeping bag based on the temperature rating it has, taking a cautious approach is always the best thing to do, particularly if you happen to be a cold sleeper. Keep in mind that it is much easier to unzip a sleeping bag to lower the amount of warmth compared to trying to increase the amount of warmth through adding layers or wearing more clothing.
