If you enjoy camping, even when the mercury drops, you will need a well-insulated sleeping bag to keep you warm all night long. Camping in cold weather presents an entirely unique set of circumstances: the risk of hypothermia and frostbite is very much real. For this blog, I’m going to take a closer look at what’s a bag perfect for cold weather camping and a few of my top picks.
The best sleeping bag for cold weather will be down insulated, water-resistant and include extra features to keep cold air out and warm air close to your body. The best sleeping bag for cold weather is one packed with down feathers, treated with a water-resistant material. Down, wither duck or goose feathers/plume, have the highest insulation value. This means you will be warmer and cozier, even when it’s snowing and ice cold outside your tent.
In this article we have 3 main types of sleeping bags we discuss. The first are the best general cold weather sleeping bags. Then next we discuss the best sleeping bags if you plan on being in extremely cold weather (there is a little overlap). And finally we discuss the best cold weather sleeping bags that are light enough to take if you are backpacking. If you are more interested in reading about one of these types of bags more than the others, I have placed links to each section below so that you can skip ahead down to that section.

Sleeping Bag Warmth 101
It’s snowing, again. You’re all cozy inside your sleeping bag, while the flakes pile up around your tent. Even though you need to hike 15 miles in the morning, you know you will be nice and rested because you have the warmest sleeping bag around. For this article, I’m going to take a closer look at what features make the warmest sleeping bag and my top pick. I hope you find this information helpful and valuable in your search for the warmest sleeping bag around.
The warmest sleeping bag is well made, down insulated with special attention to the seams and shape. While there are certain factors that make a sleeping bag incredibly warm, the best sleeping bag will vary from person to person. If you run hot, a lightweight sleeping bag may just do the trick. However, if you are always cold, you’re going to need a heavier bag to keep you warm through the night.
So, you’re in the market for a sleeping bag. If you’ve just started your search for the best, warmest sleeping bag on the market, you are probably overwhelmed by the options. Long gone are the days of the just rectangular shaped sleeping bag. While those bags are still available, it turns out the closer and tighter the bag fits around your body, the warmer you will be. There are several sleeping bag shapes: mummy, rectangular, semi-rectangular and double-wide. I’ll get into the specifics in a bit.
When determining the warmest sleeping bag for you, also take into consideration where you will be setting up camp, the weather and temperature forecast. In general, sleeping bags fall into several categories: Summer, three-season, and winter. Summer bags are rated to keep you warm in temperatures above 32 degrees. Three season bags will keep you warm in 10 degrees to 32 degrees. Winter bags are rated to keep you nice and toasty when the mercury drops below 10 degrees.
Before you even begin the search for the warmest sleeping bag determine where you will be using the sleeping bag. Your summer bag might be the warmest when you’re camping in July, however, you may be shivering in that same bag when you’re camping in mid-October in the North Cascades. Just about every quality sleeping bag will clearly rate the temperature range of the bag to help you make an informed decision.
The quality of design and construction also play a huge role in how warm a sleeping bag will be. Pay close attention to the zippers, seams and overall construction of the bag. Most sleeping bags are made of three layers, shell, insulation and lining. The shell should keep water away. The insulation should be made with high quality down or synthetic down and the lining of the bag should be soft and made of polyester- to wick away moisture while you are sleeping.
Insulation is perhaps the biggest determining factor in how warm or cold you will feel inside a sleeping bag. Thanks to advances in technology, the heavier the sleeping bag doesn’t necessarily mean it’s going to keep you warmer. In fact, some of the warmest sleeping bags made today weigh under five pounds. Some backpacking sleeping bags weigh just a few ounces. When it comes to insulation, you have two choices: down insulation and synthetic insulation. Down is more expensive, but it does an incredible job at keeping you warm. Synthetic down insulation is also really warm and waterproof; however, it tends to be bulky and heavy.
While down is my favorite choice for a sleeping bag in cold weather, it does have its pitfalls. Down is not naturally water resistant. When down gets wet, it loses its insulation value. When shopping for a down sleeping bag make sure the feathers have been treated with a water-resistant material. This water-resistant material will keep your sleeping bag dry if rain or snow makes its way inside your tent at night. In general, the higher the fill count in a sleeping bag the warmer it will be.
Down insulation doesn’t hold up well to water. So, if you go with a down sleeping bag, you want to make sure the outer shell of the bag is made of a water-resistant material. If you get down wet, it can take a very long time to dry out. There’s nothing worse than crawling into a wet sleeping bag. Synthetic insulated sleeping bags dry out quickly and are better in wet weather. Synthetic bags are also easier on the wallet than down insulation. IF you are camping in extreme cold, you are going to be the warmest in a down sleeping bag. The higher the down fill count, the warmer the sleeping bag will be. So, an 800-fill count sleeping bag is going to keep you toastier than a 150-fill count bag.
Synthetic insulation is incredibly warm as well, however, it’s bulkier than down. If you are backpacking in January, you’ll want to choose a down sleeping bag. Synthetic is easier on the wallet, making it an ideal choice for those on a budget. If you don’t have the extra money for a down bag, a synthetic bag with a liner will do the trick.
The construction and quilting of the insulation will also play a role in how warm you will be during a cold weather camping trip. Quilting keeps insulation in place- so the warmth is right where you need it while sleeping. Quilting also prevents insulation from shifting while it’s inside a stuff sack. There’s nothing worse than pulling your down sleeping bag out of your pack only to discover the feathers are all at the bottom of the bag.
Shape Of The Sleeping Bag
There are lots of different shapes of sleeping bags on the market today. Shape matters when you are trying to stay warm. A mummy shaped bag, with tapered feet and wider shoulder area, will keep you warmer than a traditional rectangle sleeping bag. Mummy bags keep the insulation close to your body, which means there is a layer of warm air close to all night long. On a really chilly night, a mummy bag will keep you toasty. If a mummy bag is too restricting, try a relaxed- mummy bag instead. The relaxed style gives you a little more wiggle room in the feet area, so you can toss and turn in the middle of the night without restriction.
The shape of the sleeping bag matters when you are trying to stay warm. As I mentioned earlier, there are several shapes of sleeping bags to help you stay warm: mummy, rectangle, semi-rectangle and double wide. The mummy sleeping bag is wide at the shoulders and chest and tapers down toward your feet. Some find the tailored feet restricting, but others find having the bag close to the body provides extra warmth. Having the bag and all that insulation keeps you warmer all-night long. When the bag fits close to the body, that warm air and down insulation stay right next to your skin. You are not wasting any space or warm air- it all stays close to you.
Rectangle and semi-rectangle sleeping bags are also great options to stay warm- however, they tend to have too much room between the insulation and your body. Rectangle bags can be connected to another similar bag for extra warmth when needed. Semi-rectangle bags are a cross between mummy bags and a true rectangle bag. A semi-rectangle bag features the tapered feet, but still enough room to move around if you tend to move around a lot in the night.
Sleeping Bag Construction
How well a sleeping bag is constructed and designed makes a big impact in keeping you warm. As I mentioned earlier, there are three layers of a sleeping bag: an outer shell, lining, and insulation. The outer shell should be made out of polyester and durable nylon. The outer shell is responsible for keeping your sleeping bag dry. The outer shell should be treated with durable water repellent (DWR) finish. This finish keeps water and moisture from penetrating the bag. Once the sleeping bag gets wet, you will start to get cold. Keeping your sleeping bag dry, means you will stay warm. Pay attention the outer shell when shopping for your next sleeping bag.
The lining of the bag is the inside of the sleeping bag. The lining should have the ability to wick away moisture, in the event you get too hot and sweaty while sleeping. Again, staying dry is critical to staying warm. The lining of the bag will most likely be made of polyester. Polyester is soft and it keeps moisture away from your body. If you get too cold in your bag, you could always add an additional a sleeping bag liner too.
The zippers and seams matter in a sleeping bag. You need zippers and seams that will keep cold drafts from finding a way inside your toasty bag. If you aren’t a seamstress, it may be difficult to know if the seams are quality and made to keep you warm. Ask the sales associate for details about the brand and construction. Also, climb in the bag before you buy it and try out the zippers. Are they easy to move up and down? Do they get stuck on the fabric? These are all important factors to consider. Most high quality, warm sleeping bags will feature zip guards that keep the zipper away from the fabric.
Also, pay close attention to how the bag is stitched together. The warmest sleeping bags have quilt-like stitching to keep insulation in one spot at all times. In other words, the stitching prevents the insulation from shifting. If the bag is not made with quilt stitching, you may unpack your sleeping bag to discover the insulation is at the bottom of the bag and you’re suddenly freezing at night. The stitching will keep the insulation where it needs to be and that means you will be warm all night long.
Extra Features for Warmth
The best sleeping bags for cold weather will feature hoods, draft tubes, high-quality zippers and a draft collar. A hood wraps your head, ears and most of your face in your sleeping bag. The hood typically has drawstring cords to tighten the hood for more warmth and protection as the weather and temperature changes throughout the night. A hood also doubles as a pillow, which of course can add comfort while camping. A draft tube keeps cold air from entering your sleeping bag through the zippers. A neck baffle is extra sleeping bag material designed to keep your neck covered and warm throughout the night. Turns out you can lose a lot of body heat through the neck area.
A hood on a sleeping bag basically covers your entire head, giving you extra warmth for those really cold nights. Some hoods will cover most of your face too. These bags are designed for ultimate warmth. The hood on a sleeping bag can also double as a pillow- keeping you warm and comfortable all at the same time. If you want to stay warm, you should opt for a sleeping bag with a hood.
A draft collar is another element added to high-quality sleeping bags to keep you warm. A draft collar is the elastic webbing around the hood of the sleeping bag. The draft collar keeps the hood in place and prevents cold air from seeping inside your bag. Draft collars are typically found on sleeping bags rated for cold weather camping. A draft tube is an inside zipper to give you extra protection from cold air. The draft tube also keeps warm air close to your body. With a draft tube, you can keep cold wind from finding a way inside your sleeping bag.
Even if you have the warmest sleeping bag in the world, you could still be cold if your bag is right on the cold ground. A sleeping pad is like a mini-mattress for camping. The pad protects you from the cold ground and keeps you comfortable throughout the night. Thanks to advances in technology, sleeping pads are lightweight, compact and incredibly comfortable. You can lose a lot of body heat through the process of conduction. Conduction happens when body heat transfers to an object or surface colder than your body temperature. To prevent this heat loss while camping, use a camping pad. You will be warmer and more comfortable while sleeping under the stars.
However, if this isn’t in your budget, there are plenty of high-quality bags for a couple hundred dollars. In this blog, I have explored the warmest and best sleeping bags for every weather condition, budget and style. A sleeping bag is an investment! One you will be thankful you made every time you go camping or need it in an emergency. Happy camping!
Cold Weather Camping
Even when the snow is falling, you’ll find extreme mountain explorers, hikers and ice climbers in search of their next adventure. Camping in cold weather is a fun way to experience the great outdoors in an entirely different way. The silence after a snowfall, the mountain peaks, and ice-covered rivers make a cold weather camping trip exciting, beautiful and a bit challenging.
When you camp in the summer, staying warm isn’t a problem. I mean, you have Mother Nature on your side after all. Depending on the region and elevation of your camping trip, it can be 60 degrees at night. Summer camping bags are all about comfort- insulation value isn’t as big of a priority. A sleeping bag for cold weather camping is all about the insulation. If you don’t have a well-insulated sleeping bag when the temperature drops you could face hypothermia, frostbite or even death.
I know that seems a bit extreme, but hundreds of people are seriously injured or die from exposure to cold temperatures every year. With a warm, comfortable sleeping bag you can rest assured you will not be chilly overnight inside your tent, even if a blizzard is rolling through. The best sleeping bag for cold weather will be durable, packed with down, and keep drafts from making their way inside. A cold weather sleeping bag should also be treated with a durable water-resistant material to keep moisture from soaking your bag. The key to staying warm is staying dry.
In addition to a quality sleeping bag, you should also make an investment in a sleeping pad. A sleeping pad prevents your body heat from transferring to the cold ground you are sleeping on. This is known as conduction. Having a sleeping pad will keep you more comfortable and warm. Sleeping pads pack well and many are self-inflating. The self-inflating pads are easy to set up- just unroll and they fill with air. However, it can take a while to deflate this type of sleeping pad. Just a quick side note from someone who’s spent more than an hour trying to fit a sleeping pad back in my pack after a camping in the North Cascades.
Cold Rated Sleeping Bags
When researching the best sleeping bags for cold weather, pay attention to the rating of the bag. In general, sleeping bags fall into one of three categories: Summer, three-season, and winter. For your reference, a summer sleeping bag is rated for temperatures above 35 degrees. A three-season sleeping bag is rated to keep you warm in temperatures between 10 and 35 degrees. Winter rated sleeping bags will keep you warm and prevent hypothermia when the mercury drops below 10 degrees.
So, you have lots of choices. When determining the right sleeping bags for cold weather, you need to think about what time of year you will be camping, where you will be camping. Also, consider your own sleeping habits. If you tend to sleep hot at night, even when it’s freezing outside you may not need a heavy duty down sleeping bag. However, if you are always chilled no matter what you’re wearing, you may need a winter rated sleeping bag for camping in October. The best sleeping bag for cold weather will vary from person to person.
The Best Cold Weather Sleeping Bags Are:
Now that you know what to look for in a cold weather rated sleeping bag, let’s take a closer look at my top picks.
REI Co-Op Magma
The REI Co-Op Magma is packed with 850-fill goose down. All that down means this sleeping bag is down with keeping you toasty on the coldest of nights. The down feathers will also hold up to wet weather thanks to a water-resistant coating. Even with all that insulation, the bag is lightweight-tipping the scales at just two pounds. The outer shell of the bag is made with a 15 denier ripstop nylon. This type of nylon is durable and tough- designed to withstand extreme weather and alpine conditions.
This is a true mummy bag- designed to contour to your body. It’s restricting, but that’s what makes it so warm. The zipper starts out at an angle, making it easy to get in and out of the bag. Inside the bag, there’s an anti-snag guard in place so you don’t get the zippers stuck when you’re trying to get out in the morning. The hood is spot on. It’s packed with soft, fluffy down feathers and it contours right to your head. An extra inner layer of material around the hood prevents heat from leaving the bag in the middle of the night.
This bag is rated to keep you warm at 10 degrees F. If you run cold, you may need a warmer sleeping bag. If you sleep hot, this will probably do the trick on those chilly fall hikes in the North Cascades or your favorite mountain range. Overall, this is a quality sleeping bag that packs a punch to the cold weather. The high down insulation fill county makes this bag a top pick for the best sleeping bags for cold weather. The bag also comes in two different lengths: regular and long. This bag rings in at $369.
Mountain Hardware Phantom Torch 3
The Mountain Hardware Phantom Torch is another top contender for the best sleeping bag for cold weather. This bag is packed with 800-fill down- making it incredibly warm, even when the temperature drops below 5 degrees.

The bag is water resistant, so the insulation will still keep you warm and dry even if there’s moisture in the air.

The bag is literally designed for Alaska and Antarctica expeditions. An extra puffy draft collar keeps heat from escaping your bag. The hood, back of the bag and foot zone are all made with water-resistant material as well. Those areas are more susceptible to getting wet while camping. The bag features an unconventional middle zipper. Some love the zipper, others don’t like it. The bag retails for $749.

For this article, I’m going to be taking a closer look at the best extreme cold weather sleeping bags on the market today.
The best extreme cold weather sleeping bags are durable, down insulated, water-resistant and feature all the bells and whistles to keep cold air out and warm air where it belongs. You’ll find the price point for an extreme cold weather is higher than that of a three-season or summer sleeping bag. You pay for what you get. The colder the weather, the more insulation, special zippers and draft tubes are needed to keep hypothermia and frostbite at bay. Extreme cold is subjective, so for this article, I’m going to narrow it down by sleeping bags rated for 10 degrees or less.

That’s why I’ve set out to find the best cold weather backpacking sleeping bags. I’ve done all the research so you can spend more time planning your next summit.
The best cold weather backpacking sleeping bags are lightweight and incredibly warm. It seems like these two requirements don’t go hand in hand, but they do. Thanks to advances in design and materials, the warmest sleeping bags are now the lightest too. When you’re backpacking, every ounce adds up. That’s why you need a sleeping bag that is lightweight without sacrificing warmth.
Big Agnes Blue Lake 25
Big Agnes is big on keeping sleeping bags warm and lightweight all at the same time. If you’re on a budget but need a bag that will keep you warm when the mercury starts to drop, the Big Agnes Blue Lake 25 is the right choice for you.
