Less is less, Don’t let anyone convince you otherwise. This is especially true when you’re carrying everything you need to live for a week on your back, which brings us to the backpack quilt: It’s a sleeping bag, but less. In many cases, a backpack quilt is all you need, and you’ve come to that They’re better than sleeping bags For all but the coldest trips.
These quilts are not like the ones your grandmother gave you. Backpack quilts are made of nylon and filled with feathers like a traditional sleeping bag, but lie on top of you like a quilt, rather than wrapping you up in the way a sleeping bag might. The benefit is two-fold: The comforter is lighter, which means less weight to carry in your bag, and in the right conditions, you may sleep better, too.
WIRED’s top picks:
Why is a quilt better than a sleeping bag?
I have a full article Dedicated to answering this questionBut the short version is that it’s just as warm, and it weighs less. The science behind the first assertion is basic physics. When you lie in a sleeping bag, your body weight pushes most of the padding to the sides. The bottom left section below you is so small and so compressed (by lying on it) that you don’t get any real insulation from it. Why, the logic goes, carry weight you’re not using?
Comforters ditch the bottom layer of your sleeping bag, and lie on top of you like a comforter on your bed at home. Quilts typically weigh less than sleeping bags and are smaller in size, making them very popular with backpackers trying to reduce weight and save space.
When is a sleeping bag better than a duvet?
When it’s really cold. The problem with duvets is drafts (they don’t wrap around you so are susceptible to cold air getting in) and their lack of backing. Drafts aren’t as much of a problem in the summer when most of us carry backpacks, which is why I like them more than sleeping bags most of the time. However, when I go out skiing or snowshoeing in the depths of winter, I carry a Subzero sleeping bag.
After years of testing, I have found which comforter is suitable for summer use. For shoulder season trips where temperatures may drop below freezing, I still use a duvet, but I use the Zenbivy, which blocks drafts better than other duvets thanks to the extra sheet and side baffles. Anytime I think the temperature will drop below 20 degrees Fahrenheit, I carry a sleeping bag.
If they have less materials, why are quilts more expensive?
Duvets are sometimes – but not always – more expensive than a traditional lightweight sleeping bag. Why do we pay more for less? In most cases, the answer is fill power. Cheaper sleeping bags often use 650 fill down, while most duvets range from 800 to 1,000 fill power, making them somewhat more expensive. However, there are some great lower priced comforters, such as REI’s Magma comforter (see below).
For summer trips, when I want to be as light as possible, the Revelation Quilt from Enlightened Equipment is my top pick. I have the 40°F version, which weighs only 19 ounces. Unlike many manufacturers, Enlightened Equipment doesn’t do this Dual temperature rating of comfort and min/max. Instead, she chooses a number in between and recommends on her website that most people use a “duvet that is 10 degrees warmer than the lowest expected temperature.” My experience with Revelation suggests that this recommendation is strong. I’ve found that Revelation keeps me warm to freezing, provided I’m wearing a base layer. If it’s colder than that, I’ll sleep in a puffy jacket too, but in summer, even in the mountains, that’s rarely necessary.
The Revelation has the ability to lie completely flat on warm nights, which is the method I usually use. The foot box has a zipper and a 20-inch drawstring, allowing you to close it to create a tight (read snug) space at your feet when you need it. There are also straps that form a loop and wrap around your sleeping pad to keep the oracle in place. The straps are separate, which is nice because I don’t use them half the time, but it makes losing risky. It’s also a bit different from other systems I’ve tested in that it goes around your board (rather than directly below it) and then cuts the apocalypse onto it. I don’t like sleeping on the belt, so I use these straps “wrong” and put them under my pillow, ignoring the loop feature, and they work great. On warmer nights I don’t care about the straps at all, quilts are about flexibility after all.
Revelation is available in an almost endless array of configurations, with temperatures ranging from 50°F to 0°F. You can also get different lengths (short, regular, and long) and different widths (wide and regular), and choose between 850 fill power and 950 fill power. A draft collar is available in bags below 30°F. I tested the 40°F model with 850 fill power, which weighs 19 ounces and costs $370. It’s also worth noting that there’s an option to create a completely custom, made-in-the-USA version using your exact dimensions, fill strength, and fabric color preferences.
When the temperature drops below freezing, I turn to Zenbivy’s various sleep systems. In my neck of the woods, freezing temperatures can extend well into June and into early September, so I spend a lot of time in my Zenbivy quilt. I’ve tested every model the company makes, and part of the beauty of the Zenbivy system is that you can mix and match different comforters and covers depending on what works best for you. My favorite set is the Light Quilt (the convertible version, which opens flat), paired with the Ultralight Bed half sheet/hood. I prefer the 10°F version for both. This ultimately results in the most versatile and lightweight range of temperatures I tend to encounter (using half the sheet saves me 6 ounces over the whole sheet). However, if I were backpacking mostly in the mountainous West or in warmer climates, I would choose the 25°F option.
