10 Best Backpacking Sleeping Bags
1. SEA TO SUMMIT SPARK 2
Small pack size
Interior fabric feels very nice against the skin
The Sea to Summit Spark 2, in our opinion, is one of the best sleeping bags we looked at for several reasons and is the way to go if you are desiring an incredibly light sleeping bag to pack up and backpack with. It doesn't offer all the bells and whistles that other bags offer, but this is because it forgoes some of the perks in order to be light. It looks just like the Spark 2, but it is made to be warmer.Read more
What is special about the Spark 2 is that it is designed to offer you warmth, so that it can be used all year round, but it only weighs 1.38 pounds. Weight is what you're looking at when it comes to sleeping bags you'll be carrying long distances. This is one of the reasons we picked this as the best sleeping bag in our guide. This one could fall into the ultralight bag category.
If you prefer mummy bags, the main benefit of this particular sleeping bag is its compressed packing size. It's 1/3 size that packs down to fit in a compressed sack that can fit in the palm of your hand.
Like most of their sleeping bags, this comfortable sack feels soft and comfortable to the skin. It is 100% nylon that is treated with DWR, which will offer you protection from moisture. The inside is filled with 850 dry down and European goose down. This means that the sleeping bag keeps you warmer on those colder nights out backpacking and camping.
There are many factors that keep you warm in this mummy bag. A combination of the 850+ ultra dry down, the 10D nylon treated with DWR shell, 1/3 length zipper, and baffle construction all work together to keep you warm and cozy in the cold and beautiful environments. If you are looking for a sack that offers you a lightweight option that can be packed down to take up minimal room, then this is your perfect choice. It features a 3YKK zipper that is durable. And the Spark 2 will keep you feeling very warm with its premium down fill. Maybe this is a bold statement, but we felt like this was one of the best sleeping bags that we looked at.
2. MOUNTAIN HARDWEAR HYPERLAMINA FLAME 20
Zipper can snag
Mountain Hardwear's Hyperlamina Flame 20 is a synthetic, mummy-style sleeping bag, which is affordable and well designed. It is efficient and innovative, as well as built with high-quality material. Synthetic bags are generally best if the hiker wants confidence that they will stay warm in wet conditions. Along with many others, that is one of this bags best qualities. It also has a ½ zipper located on the front of the Flame and a hyper-ergonomic foot box. The exterior was designed without seams or stitches, which makes it more water resistant and helps with retaining heat. Reviewers felt the fabric that the inside and outside were constructed with was comfortable and soft of the skin. Other synthetic bags can come with a heavy and smothering feeling, but the Hyperlamina was neither. Overall, this is one of the best synthetic sleeping bags out there for an affordable price.Read more
For the fast and light hiker who wants a synthetic bag, this is the best one on the market. At 43 ounces, it is not the lightest on the market. However, with a synthetic sleeping bag, you can rest assured that if it went wet, you will not be cold. Synthetic insulation insulates far better if moisture enters when compared to down bags.
Synthetic filled sleeping bags are a bit tougher to pack small compared to down filling. When in its packed size, it is 7×16 inches, which is comparable to lower quality down bags. If the packed size is really important to you, a down filled sack may be a better option.
Most reviewers noted that the half zip design of the Hyperlamina sleeping bag made it easy to get in and out of. The zipper runs chin to belly button length and is located on the chest side. When fully zipped, the end of the zipper is protected behind the draft tube, so it doesn’t poke users all night. Reviewers liked the location of the zipper compared to other bags, but the short zipper does eliminate the option of venting the lower body on warmer nights. The zipper was also prone to snagging the outer material, which can lead to poor long-term durability if it rips the material. Reviewers reported that they thought the synthetic fill was overall very comfortable and that it maintained excellent loft.
A little pack weight and size is given up for warmth. Testers agreed that this is one of the sleeping bags that actually did live up to its 20-degree rating. Thermal-Q fill keeps users remarkably warm, even when it is below freezing outside. The construction also has no stitching, so there are no small holes for cold air or moisture to sneak in through. Reviewers noted that the design of the hood was well thought out. Users felt that the hood conformed to their head without limiting movement or vision. The hood has a passive draft collar, which is secured by a velcro closure. Reviewers felt the draft collar was comfortable and kept the warmth inside. They also noted that the velcro strip was strong enough to keep the tube in place all night. The Flame provides a slim, snug fit, which helps keep the person inside warm. Most people loved the snugness (slimmer people), but some didn’t like that it restricted their sleeping movements.

Criteria Used for Evaluation
Sometimes, every ounce in your pack counts. An ideal weight for backpacking sleeping bags is two pounds or less. Carrying more weight than needed, can slow you down and wear you out. Many reviewers find the weight to be more valuable than the packed size, which is one common complaint about mummy-style sleeping bags. Finding one that is light enough, but also gives you the space you need to sleep comfortably can be difficult.
Overall when looking at investing in a new sleeping bag for your next backpacking trip, keep the weight of the bag in mind as it will make all the difference as even though these sleeping bags can be compacted down for easy transport if they are heavy they will cause you discomfort. The last thing you want after hiking for hours in the wilderness is to be uncomfortable. Going a bit further with it, you really want to consider the warmth-to-weight ratio that your choice offers. You can find a bag that insulates properly while still maintaining a decently lightweight package. Lightweight sleeping gear is a must. We are seeing more and more people going with the more ultralight sleeping options, as it saves a little more on the weight that you'll have to carry. Just remember, the best sleeping bags for backpacking are going to be the ones that have an acceptable warmth to weight ration. you have to carry it, and it has to work.
Depending on how you will be exploring the outdoors, the size of your crucial items is incredibly important, and this goes especially for sleeping bags. The only instance that you wouldn't be stressing about this is if you were driving to a campsite or didn't have far to walk. If you have a long trek ahead of you, you will need to plan ahead with water, food items or cooking supplies, clothes, first aid or emergency kit, and a tent. Fitting all of this into a 30L backpack can be difficult. A great solution to this headache is a sleeping bag designed specifically for backpacking. The packs we have included on our list are lightweight and most pack down quite small. If the packed-down size is still too big for your backpack, we recommend using a carabiner to attach the sleeping bag to a strap of your backpack. As long as you choose a lightweight option, this shouldn't be a hassle and will save you space inside your bag. For the taller people out there, you should make sure your pick fits comfortably. That way you can get the best sleep experience you can get on your trek.
The material of your backpacking sleeping bag plays a big roll in how comfortable you will be on your expedition. We recommend bags with a DWR coating. If you get stuck in the rain or accidentally lay your bag down on a wet surface, the water will not seep through and you can still sleep cozily. The better the material, the more versatile sleeping bag you'll have fo all kinds of different occasions.
It's what's on the inside that really counts, right? There are a few different fillings available for sleeping bags. The most popular are down filling and synthetic. Down filling, especially goose down, is said to be the warmest and most luxurious. The only downside to down filling is that it can move around and you will have to re-position the feathers if you notice any cold spots. A synthetic filling is typically more cost-effective. While down fillings have seen recent improvement with moisture, a synthetic filling is known to keep you warmer in the case that moisture seeps in. But, you do want to find a bag that is breathable, especially for the warm summer nights. This is also where choosing the right items for the location is important.
Comfort is key for all of this kind of outdoor gear! Check whether it has zippers and what the length of them is. This will determine what type of ventilation is possible and how easy or hard it will be to get in or out of the bag. Some bags have draft tubes around the zippers and draft collars around the hood to improve insulation. Sleeping pad loops or pockets are also convenient so you do not roll off the pad. What you wear to bed, metabolism and if you use a tent can all affect a person’s comfort level while sleeping in nature as well. Another good thing to think about is that the materials can also dictate the temperature ratings. Also look for durable materials, such as abrasion resistant panels and a ripstop nylon shell. Many of the newer and more durable materials are light enough for those ultralight sleeping options.
Like all of your backpacking gear, your stuff has to work in not so great conditions. Look for sleeping bags that are versatile so they can be used through multiple seasons and in different weather. If you are looking for a specific temperature sack, winter, for example, check the temperature rating or EN number on for a general guideline. Also, consider the type of hood and the types of zippers for venting. You want it to be warm enough on a cold night, but also comfortable enough on a summer evening. This is really one of those factors that should be considered with all of your outdoor gear.
Overall you are looking for sleeping bags that are fitted for the season as this is the most efficient way to make sure you stay comfortable. When backpacking sleep is one of the most important things you can do to recharge your energy for the next day's activities and journey. So make sure your sleeping bag is fitted for the season you intend to use it, that way you will be sleeping easy. The weather resistance properties can also influence the temperature ratings of a particular bag. To get the best sleep experience on the trail, the weather resistance matters. A water-resistant shell is also a good idea, just in case you find yourself waking up in a wet area in the morning.
You should also put some thought into where you're heading. Are you going to be in cold weather, moderate temps, or are you heading into warmer weather? If you stick to warm weather, you should be able to get something pretty light in overall weight.
Expert Interviews & Opinions
Yes, of course, you want a sleeping bag in your favorite color or design, but that is the least important criteria when looking for a backpacking sleeping bag. Don't forget that your eyes will be closed 90% of the time you are using it.
Know the type of weather you're facing before you arrive. If your sleeping bag has a temperature rating of 30 and the low for the night is 0, you may wake up chilly. In this case, it would be best to pack an extra blanket or extra warm long johns.
About 45% of your body heat escapes from your head. If you will be in an especially cold environment, it is recommended to invest in a sleeping bag with a hood. If you find yourself in a slightly warmer environment, you can usually roll or fold up the hood as a make-shift pillow!
Other Factors to Consider
You can't always guarantee the best sleeping conditions out there. You will have to decide whether you want a synthetic vs down (goose or duck) insulated sleeping bag. Despite advances in synthetic materials, down fill continues to provide the best warmth-to-weight ratio of any insulation available. It is also easier to compress and excels in the cold.
The one weakness of down filling is that it loses its ability to maintain warmth when it gets wet if not treated correctly. Synthetic, on the other hand, is quick-drying, maintains decent temperature ratings when wet and is non-allergenic. It typically isn’t as light or compressible. Another thing to look for when it comes to down insulation is its fill power. This number is typically between 600 and 900 and measures the amount of loft or “fluffiness” of the down insulation. You also have to decide what shape is more comfortable, traditional or mummy bags. One thing to keep in mind with the mummy style is that many side sleepers are less comfortable in them. One item that will absolutely add to the comfort factor is a ground pad. There are a ton of really great sleeping pads to choose from that won't add much weight to your pack.
Another important factor to think about with just about all of your backpacking gear should be the overall durability. In general, durability should be a major factor going into choosing all of your trekking gear. After all, what good is something if it falls apart at the time you need it the most.
The materials should be of good quality. You might even consider holding off on buying a product right when it is released onto the market. Sometimes it is smart to wait a bit, letting others put the gear to the test and looking at their reviews of how specific gear performs as well as any shortcomings that might be discovered. You probably don’t want to be the first one to discover that a what you paid a lot of money for, doesn’t quite hold up to your expectations. Let us try them out first, then you will have the info available to research. You can add to your sleeping bag's durability a bit more by also putting a pad under. Yes, it is more to carry, but many of the sleeping pads available today are super light and compact.
Frequently Asked Questions
q: Do I need to use a sleeping pad?
If you can afford one, you should always use a sleeping pad to protect the underneath and to add warmth. It will keep you warm and safe when temperatures get very cold and also add an extra level of comfort.
You have to keep in mind that when you are backpacking, even though you will be sleeping in a tent, the tent will not have a padded ground pad. Most likely you will be sleeping and feeling whatever ground you decided to lay your tent over. So if you have extra space and want to have a comfortable sleep without twigs or roots poking you in the back during the night, it may be a great idea to invest in a sleeping pad for extra support and comfortability.
q: What do I need to know about the zippers?
Most sleep sacks have zippers that need to be zipped with care. Although they are made not to snag the material, using extra caution and using patience will ensure no snags or rips happen from the use of the zipper.
There is nothing worse than getting to your campsite after a day of backpacking and getting ready to get a good night rest and when you slip into your sleeping bag and go to zip it up, the zipper breaks and you can not completely wrap yourself in your sleeping bag. This can cause your sleeping bag not to maintain your body warmth and keep you warm in colder temperatures, so when you go to invest in a new backpacking sleeping bag, make sure you check the customer reviews to get an idea of the quality of the zipper.
q: How can a liner help me?
If you have your eye on a sleeping bag that includes a liner than this is always a positive. Using a liner will help keep dirt out and add to the warmth if needed. Liners can help retain 5-15 degrees F of heat. Once your trip is over, simply wash your liner and you are good to go.
q: Should I wear clean clothes when getting into my sleeping bag?
When getting ready for a good nights rest after a long day of adventuring, it is best to clean yourself as much as you can as you may have a lake near you or a portable shower. Then have a fresh pair of clothes that you can change into as that is the best way to be comfortable in your sleeping bag. The last thing you want to do is get ready to go to sleep and still be wearing the clothes that you hiked in all day. The sweat, dirt, and muck will not only have you uncomfortable but can also stink up the inside of your sleeping bag and if you are sharing your tent with others, this may be a nuisance to them as well as yourself.
q: How often should I use my compression sack?
You should compress your sleeping bag into your compression sack only when you are traveling. If you have decided to stay at a campsite for a couple of days, it is best to leave your sleeping bag unraveled inside your tent. If you are moving to another campsite it is best to compress your bag up as it will be easier to transport that way.
q: Do I need to worry about keeping my bag clean?
Keep it as clean and dry as possible. Let it air out and dry completely before rolling up and storing for a long period of time. These tips will help improve longevity and make your investment worthwhile. The more you take care of it, the more it will take care of you. Happy Backpacking!
