Best Lightweight Sleeping Bag for Backpacking

Table of Contents

Your sleeping bag is one of the most important – and one of the bulkiest – items you’ll need with you on a backpacking trip. This means you need to pay careful attention to the weight of your bag when making your choice.

Of course, you also need to be sure the bag is warm enough, which can add weight. The good news is the average sleeping bag has enough insulation to keep you comfortable in most climates so that you can focus more on the weight you’ll be carrying as opposed to the filling when shopping for a lightweight sleeping bag.

So how do you find the right backpacking bag?

It can help to evaluate bags based on a few of their most important features:

Weight and Insulation

When making decisions about a sleeping bag’s warmth, make sure to use the 20-degree rule of comfort. This rule means that if a sleeping bag says you’ll survive the night at a specific temperature, this doesn’t mean you’ll be comfortable sleeping in that temperature. To determine the comfort rating based on the survival number you’re given, add about 20 degrees. For instance, if a sleeping bag is listed as suitable in temps as low as 10 degrees, you’ll probably be comfortable in it with no additional layers at about 30 degrees.

Do you prefer a down or synthetic fill? Down is lighter and warmer, but not everyone wants a bag filled with down feathers. Synthetic might be more cumbersome and not as warm, but it performs better if it gets wet, and bags filled with synthetic materials tend to be cheaper.

There synthetic and down-filled bags, and as you might guess, there are pros and cons to each style. Down tends to be lighter, but it doesn’t hold up as well when it gets wet. Down is warmer, but some people are ethically opposed to it. Synthetic is cheaper, but many people find it to be an inferior all-around. You need to decide what’s important to you and choose your sleeping bag based on that.

Though five pounds might not seem like a lot when you’re shopping for a sleeping bag, when you’re carrying it along on your hike with everything else you need to bring with you, the difference between two or three pounds and five pounds can be significant. The key to getting the right bag is to choose the lightest weight possible within your budget and within the level of warmth you need based on your usual hiking destinations.

Ultralight Backpacking Sleeping Bag


Everyone wants a bag that can be compressed down into a small bundle, whether they are hiking or not. But if you are walking and you have limited space on your back, compressibility in a sleeping bag is essential. The warmer the bag, the bulkier it will be. Some bags offer straps and ties to make compression easier. Compression doesn’t necessarily affect weight, but it does affect the efficiency of packing and how much you can carry with you in total.

Interior space

You’ll want to consider how much room you’ll have in a given bag. What the “right” amount of space is in a sleeping bag is a matter of personal preference. Some people love the idea of being tightly cocooned into their sleeping bag, while others loathe the thought of it and need room to thrash about all night long. Keep in mind, the tighter the bag, the warmer it will be, so you might need to compensate for temperature rating if you prefer a looser bag.

Also, make sure you take into consideration both the length and width of the bag. You might have plenty of room to spread out your arms, but if your toes are pressed up against the bottom of the bag, you won’t be that comfortable. Also, be sure to allow for the varying sizes of your body. People usually aren’t the same width at their ankles as they are at their hips and belly, so you want to make sure something fits all parts of you.

Zipperless sleeping bags are all the rage now and understandably so. Zippers are just one more thing you need to worry about when you’re camping. They break, and they get caught on things, and you’ll find yourself wasting time or being stuck with a bag that can’t do its job because of the zipper. If possible, opt for a zipper-free sleeping bag. If you prefer a bag with a zipper, stay away from more substantial metal zippers. Nylon and plastic zippers tend to be lighter weight and are more durable. If you must choose a sleeping bag with a zipper, make sure it’s one that’s coated, and that offers some kind of guarantee that it will work properly.

How easy is the bag to get into and out of


If you are traveling with a sleeping pad, does the bag offer a way to fasten the pad into place? Both pouches and loops for attaching your pad tend to add weight, but might be worth it if it makes for a secure evening of sleep.

Do you prefer a mummy or quilt style bag? You need to decide which shape of bag you prefer. You have plenty of options: mummy, rectangular, and quilt, to name a few. Again, they all have pros and cons, and in many ways, it comes down to a matter of personal preference. The conditions in which you’ll be backpacking or camping are also an important consideration when choosing the type of bag that’s going to offer the performance you need. Mummy bags offer head coverage and therefore tend to be warmer, but they are too constricting for some sleepers.

Now that you have an idea of what’s essential when it comes to choosing a lightweight sleeping bag check out our top recommendations when choosing an ultralight sleeping bag for backpacking.

Getting a good night’s rest when you’re camping is essential. This is especially true for camping trips that aren’t all about relaxation. If you’re hiking or doing any physical activity during your trip, you’ll want to be sure to get plenty of sleep at night. A good sleeping bag is essential for this.

How Do You Choose The Best Sleeping Bag For Adults?

There are several things to consider.

First, you need to know what type of sleeping bag is going to offer you the best opportunity to get a good night of rest based on where you are sleeping. How cold are the nights at your campsite? Will you be camping in a tent? Will you be sleeping in an RV, vehicle, or tent? Do you have a sleeping pad to put beneath your sleeping bag?

All of these things are important considerations when you are shopping for a sleeping bag.

There are two main factors you’ll want to evaluate when choosing your sleeping bag: shape and insulation

We’ll start with the shape.

Sleeping Bags for Adults

Sleeping bag shape

When most people think of sleeping bags, they picture a cocoon-like swatch of material that can be zipped up to cover the sleeper fully. But there are different shapes of sleeping bags, and each serves a different purpose. The goal is to be as comfortable and temperature-controlled as possible when in your bag. You might even want to “try on” a few bags before you buy.

  • Rectangular: Offer plenty of room for legs and arms, many can be unzipped entirely and used as blankets
  • Semi rectangular: AKA the “modified mummy” or “barrel” bag, this type of sleeping bag covers a variety of shapes and offer a blend of warmth and roominess.
  • Mummy: A bag with a snug fit that fits tightly around your body, it’s known for being very warm
  • Double bags: These bags are made for two people or one person who needs a lot of extra space


Idea of what shape bags

Now that you have an idea of what shape bags are available, so let’s talk about insulation. The insulation in a bag is going to be one of the most important factors concerning how warm and comfortable the bag is when you’re using it.

The two main options for insulation are down-filled or synthetic (human-made). Synthetic insulation bags tend to be more affordable, dry fast, and are non-allergenic. They are also useful even if they get wet. Down-filled bags are lighter weight, don’t work as well when wet, and are more durable over time. They are also easier to compress so you can pack them easily when you are limited on space.

Are down-filled bags ethical?

It’s understandable why vegans and other people concerned about the ethical treatment of animals might be worried about down-filled bags. Most of the more reputable brands tend to monitor the treatment of the animals used to provide the down. Bags that feature the RDS (Responsible Down Standard) or TDS (Global Traceable Down Standard) label are more trustworthy in their claims of ethical down sourcing.

Other Things to Consider

In addition to the shape and the insulation, you might also want to consider other features in your sleeping bag. For instance:

Zipper: Multiple zippers on a bag made it easier to adjust when you need to cool down or warm-up. It’s also a good idea to look for a bag with a zipper that isn’t likely to snag or break.

Pocket: Many bags come with pockets, so you can keep what you need close by without it getting lost in your sleeping bag. The most common use of sleeping bag pockets these days is for a cell phone.

Sleeping Bag Hood: Bags with hoods tend to be much warmer, so if you plan to camp in three or four seasons, it’s best to look for a hooded bag.

Stuff Sack: This is a bag that comes with your sleeping bag that allows for easy packing. Most sleeping bags are rolled, but many of them tend to come undone when jostled around. A bag prevents this from happening.

Sleeping Bag Liner: Some bags come with a soft sleeping bag liner to enhance warmth and comfort. You can remove it during warmer weather.

What Are The Best Rated Youth Sleeping Bags?

Anyone who has taken kids camping with them knows how fun it can be – and how challenging. Camping is an excellent activity for families with kids of all ages, but it takes some planning and some investment in the right kind of gear. Letting kids use adult equipment and hoping it works out isn’t always the best or safest solution. And when it comes to sleeping bags, it could mean nobody gets a good night of sleep.

Instead, you should invest in a youth sleeping bag that is specially designed for little sleepers. Kids’ sleeping bags aren’t as expensive as the adult versions, so you’ll get exactly what your child needs for a reasonable price.

But how do you choose an excellent youth sleeping bag?


There are a few essential factors you’ll want to consider:

Weight and Insulation

Usually, the weight is only a concern with sleeping bags when you’ll be hiking to your campsite. Often, that’s not something you do with children in tow, at least not for long distances. This means the weight of the sleeping bag isn’t as important. Not to mention, children’s bags are much smaller, which means the weight is automatically reduced.

Insulation is still a concern because it can affect the warmth and comfort of the bag. This is especially true if the bag gets weight. Down-filled bags rarely do you much good, so you’re better off choosing a children’s sleeping bag that’s insulated with synthetic materials. This is not only a good idea because of weather conditions, but also because of spills. If you do opt for a down-filled bag for a kid, make sure it’s water-resistant.

Make Sure Your Sleeping Bag and Sleeping Pad Are the Correct Size

Temperature Rating

The last thing any parent wants when camping with their child is to wake up to complaints of being too hot or too cold. And if the sleeping bag is not appropriate for the temperatures you’ll be camping in, it can be a downright dangerous situation. This is why it’s so important to check the temperature rating on the bag.

Most sleeping bags use the EN 113537 scale to determine temperature rating. It was developed in Europe, but it’s used for most North American brands now, as well. It provides three temperature ratings, including:

  • Comfort rating, which is the lowest temperature the bag will keep the average cold sleeper comfortable at.
  • Lowest-limit rating, which is the lowest temperature the bag will keep the average warm sleeper comfortable at.
  • Extreme rating, which is the average temperature the bag is safe to use it.

When it comes to the temperature of a kid’s sleeping bag, you can also consider the seasonal rating. Most three-season bags are comfortable in temperatures as low as the 20s, approximately, so they are usually suitable for spring, summer, and fall camping in most locations.

However, if you plan to camp during the winter in a location with colder conditions, you’ll need a bag that’s suitable for the teens or lower. For a child, it’s a good idea to get a bag that can handle subzero temps if you plan to camp during the winter. Kids tend to be warmer sleepers, but you want to make sure they are safe and uncomfortable if you’re facing extreme temps.


You’ll want to consider the form or shape of the sleeping bag. Most kids’ bags are fairly standard sizes. Kids’ body types aren’t as varied as adults, so you don’t need to worry about extra-long or extra-wide bags. You will want to make sure the bag fits snugly around your child’s body because this helps to hold in the heat.

Heat loss is one of the main reasons it’s not smart to allow a child to use an adult sleeping bag. The large empty spaces allow pockets of cold air to get into the bag, and you aren’t able to use body heat as efficiently when the bag isn’t snug to the body.


Finally, you’ll want to consider the cost of the bag. Because they are smaller, most youth sleeping bags tend to be less expensive than adult bags.  You can get high-quality children’s sleeping bags for as little as $50 to $100. This might seem like a lot, but when you consider the adult version of the same bag would run you up to $400 or $500, it’s easy to see how much you’re saving on the smaller bag.

The cheapest bags, the ones you usually find with novelty characters for about $20 to $25, aren’t suitable for outdoor camping. They’ll work for indoor sleepovers, but if your child is in scouts or you’re planning a family camping trip, you’ll want to spring for a high-quality bag that’s a little more expensive.

Best Backpacking Sleeping Bag Under $150

Backpacking and camping are great hobbies, but like most hobbies, they can get expensive. The good news is backpacking is a great way to save money overall. After all, there are few things more cost-effective than walking through the wilderness and sleeping in the great outdoors instead of in a hotel. Camping and backpacking are the most affordable options for traveling, especially if you’re budget-conscious when choosing your gear.

The trick to planning a successful backpacking trip that is affordable is to find quality gear at a reasonable price. You don’t want to buy gear that is too cheap because you’re going to get lower quality. That can make things pretty uncomfortable when you’re spending time outdoors, especially if you intend to sleep under the stars. It can also be dangerous if you sacrifice certain features in equipment to save yourself money.

So, is it possible to get a quality sleeping bag at a reasonable price? Can you find something that will suit your needs for under $150? We think so.

Comfortable Sleeping Bag Under $150

We’ve put together a list of our favorite backpacking sleeping bags for under $150

Some are significantly under that price point. But first, let’s consider what you should look for in a sleeping bag.

Lightweight and Isolation type

Perhaps the most important consideration for backpacking sleeping bags is weight. You want a bag that is lightweight as possible while still offering appropriate warmth and protection. Backpacking means you’ll be carrying everything you need for your time away on your back, so the lighter, the better for all of the items. And since your sleeping bag is one of the largest items you’ll have, it’s imperative you choose something as light as possible.

The type of insulation in your bag is going to affect a few things. Down-filled bags tend to be warmer than synthetic, so if you are concerned about cold weather, you might want to lean toward natural filled bags. Down filling tends to be lighter weight, too. However, down bags don’t stand up to wetness as well as synthetics do and they are a lot more expensive, so you might not have that many down options in the price range. You can find a quality synthetic filled bag at less than $150, and the chances are that’s your best bet if budget is an issue for you.

Temperature Rating

As you want to consider the season and conditions you’ll be camping in and choose a bag with an appropriate temperature rating. Chances are for less than $150 you aren’t going to get something suitable for subzero temps, so limit yourself to camping in three seasons until you’re able to afford a more highly rated bag. However, for this price point, you can find plenty of fantastic bags that will keep you comfortable in temps below freezing. Some bags are even safe for camping in temperatures as low as the teens.

Remember, when choosing a bag, consider the 20-degree rule. If a bag says it’s rated for as low as 10 degrees, that means you’ll probably be warm and cozy in temps as low as 30 degrees. You’ll survive in colder weather, but you’re not going to get as good a night of sleep, especially if you tend to be a cold sleeper.

Size and Shape

You’ll want to consider two factors when looking at the size of the bag: the size it is when it’s packed up and you’re carrying it, and the size it is when it’s unrolled and you’re sleeping inside of it. Obviously, one affects the other. You want a bag that’s large enough to fit your body comfortably, but small enough to help you retain heat and that fits easily on your back with your other equipment.

The shape of your bag can affect comfort and how warm the bag can keep you. Mummy bags tend to be warmer, but they are smaller overall, and many sleepers find them too constricting. Mummy bags are also usually lighter weight because fewer of them feature zippers. You can find bags of any shape in this price range, so it really comes down to a matter of personal preference.


Finally, you’ll want to evaluate the durability of a bag. Consider what it’s made from and what other campers have had to say about the bag. Even though budget is an issue, you’re still investing up to $150, which is a solid chunk of change for most people. You’ll want to get a sturdy, long-lasting bag for this price, even if it lacks some of the features available in more expensive bags. You’re looking for simple and high-quality, as opposed to a cheap knock-off of a bag with all the bells and whistles.
