Criteria Used for Evaluation

Weight

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.

Size

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.

Materials

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.

Weather Resistance

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.

Weight
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.

Size
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.

Materials
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.

Weather Resistance
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.

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.

Weight
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.

Size
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.

Materials
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.

Weather Resistance
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.
