The oxygen is thinner than you’re used to, it’s always cooler than normal, the air is decidedly cleaner, and you probably had an exciting day of trail riding or trekking through the backroads. You’re beat, you’ve had a great meal under the stars, the campfire has reduced itself to smoldering embers, and you’re ready to hit the sack. But what sack? It’s time to check out our options for sleeping bags. There are many to choose from and, hopefully, you’ve picked the sleeping bag that fits not only your style of camping—hiking, hyper-light backpacking, base camping, car camping or maybe just being under the stars next to your rig—but that it’s also one that fits the temperature range you’ll most likely find yourself in.

Therefore, they can’t always be equally compared to each other. In Europe, all manufacturers rely on the European Norm (EN) 13537, which is a standard rating system and testing method, developed so consumers can equally compare sleeping-bag temperature ratings. However, it is a little complicated. Essentially, the EN 13537 evaluates each bag, and classifies it via three levels: Comfort, Lower Limit, and Extreme. The “Comfort” rating is for women, who need more insulation to stay warm; the “Lower Limit” is for men, and suggests the lowest temperature at which a man will be comfortable; while the “Extreme” limit denotes the coldest temperatures a person could remain in a sleeping bag without freezing to death. Keeping it Warm On the other hand, in the United States, the temperature rating is a number (in degrees) used to describe a sleeping bag that will keep its user warm at a specific outside temperature. If the rating is 30 degrees, it means that most users would remain warm if the outside temperature dropped no lower than 30 degrees. It makes a couple of assumptions, specifically that the user is wearing thermal undergarments and the bag is resting on a pad. Typically, sleeping bags marketed in the U.S. (or manufactured there) can be divided into three categories with their associated temperature ratings: Summer, Three Season and Winter. “Summer” bags can withstand temperatures no lower than 35 degrees; “Three Season” bags are good between 10 and 35 degrees; while a “Winter” bag can keep its user warm at 10 degrees and below. These ratings are by no means set in stone. They may vary from manufacturer to manufacturer, which is why the temperature ratings of the sleeping bags we featured here sometimes show several different ratings (EN 13537 and standard). Even then, they are meant to be a suggestion. Only you know what level of cold you can withstand, and how your body reacts to various temperatures. [divider] [/divider] Insulation: Down vs. Synthetic Like anything, you will discover proponents of both kinds of fill insulation, as there are campers and hikers who will swear by each one. Down Insulation is not made from duck feathers, but instead the fluffy undercoating that resides between the feathers and the skin of the duck (or goose or other waterfowl). It works very well because it creates myriad air pockets that trap air to be warmed by your body. Also, since its job is to keep a water-born animal warm, it is breathable, which allows moisture to easily escape. Very few manmade fibers can match down’s warmth-to-weight ratio and longevity. If properly cared for, down insulation will last a very long time. However, down has its—ahem—downsides. Though it is breathable, it doesn’t do well after it gets wet, as it takes a long time to dry and is difficult to clean. Because lower-quality down can include dust, particles and debris, people can suffer allergic reactions in its presence. As a result, high-quality down can be more expensive than synthetic. [/cbtab] Synthetic Insulation Synthetic insulation has been advancing in quality in the last few years. Essentially, it is polyester threading that is shaped to mimic down insulation, but its various creators struggle between shaping thin and light strands to trap and warm air efficiently, and shaping thick strands that remain puffy and last longer. A plus for synthetic is that it is water resistant, and will still retain warmth even when wet. It is cheaper and easier to maintain and clean, not to mention completely hypoallergenic. Synthetics, however, are heavier and bulkier than down; a similarly rated down sleeping bag will pack smaller and lighter than one with a synthetic fill. Since there are a variety of companies that produce many different kinds of synthetic insulation (Dryloft, Thermoloft, Polarguard and Thermolite, to name a few), research the pros and cons of each one before making a purchase. [/cbtab] Down Fill Power Like everything in the sleeping-bag industry, down insulation is rated according to “fill power,” which is represented by the number of cubic inches one ounce of down will occupy. For example, if a sleeping bag has down with a fill power of 800, that means that one ounce of down takes up a volume of 800 cubic inches. Most outdoor gear and apparel companies use only goose down, which has a minimum fill power of 500 to 550. Goose down fill power can go as high as 800. The higher the fill power, the better the down will insulate, because there is less chance of cold spots forming (spots where the down has shifted away, leaving an uninsulated area). If a label doesn’t specify fill power, it is usually because the down falls in a range below 400 cubic inches or the item contains less than 75-percent down. Down is marketed in a few different grades. For example, a 90-percent goose-down garment will consist of 90-percent down, and the remaining 10 percent will be small pieces of feather that were not removed during manufacture. The higher the percentage of down, the better the warmth-to-weight ratio will be, and the higher the cost.][/cbtab][/cbtabs] Editor’s Note: A version of this article first appeared in the Winter 2016 print issue of Tread Magazine.
