Sleeping bags are an essential part of any camping trip, but when most people think of sleeping bags, they think of heavy, down bags with a below-zero temperature rating.  While many of them are constructed with cold winter nights in mind, there are just as many that are meant for camping in warmer climates.

If you’re looking for a lightweight and comfortable sleeping bag that won’t make you overheat, the best summer sleeping bag will keep you sweat-free during your next summer camping trip. Sleeping bags are important because not only do they provide you with a comfy night’s sleep, but they also act as an extra layer of protection between you and the elements of nature.

Things to Consider Before Buying

There are several factors that you should think about when looking for a summer sleeping bag. Not all sleeping bags are made equally, and different situations can call for different kinds of sleeping bags.

Take into consideration the factors below to find a sleeping bag that is comfortable and suited for your individual needs.

Insulation

There are two general types of insulation that sleeping bags are made with: synthetic and natural. Below we lay out the pros and cons of both, and which you should choose for your sleeping bag depending on your camping needs.

Sleeping Bag

Synthetic is the choice insulation of most campers because of its durability and budget-friendly nature. It’s also non-allergenic, making it a great choice for campers who are sensitive to other materials.

The downside to synthetic insulation is that it doesn’t compact down to a very small size when compared to the natural down insulation. This makes it harder to stuff inside a backpack when going on longer hikes.

The other insulation material is made of natural goose feathers and is often more expensive than its synthetic counterpart. Goose-down insulation is great because of its insulation abilities and the fact that it can be easily compressed into a compact size perfect for backpackers.

Compressed Sleeping Bag

The downside is that it’s not water-resistant, and therefore not great for all weather conditions. Although in recent years, some goose-down sleeping bags have been treated with water-resistant protection to help protect your sleeping bag from rain and moisture.

Temperature Rating

The temperature rating of a sleeping bag is meant to tell its users what the lowest temperature it will be able to keep you warm and comfortable in. Although many factors go into this temperature rating—including your body size, metabolism, and the additional features you use with your sleeping bag such as a pad, warm clothing, etc.—there are three generally accepted temperature ratings for sleeping bags outlined below.

Summer (+35°and higher) sleeping bags are meant for warmer weather and terrains where you don’t have to worry about the temperature dropping overnight. They are perfect for the warmer summer and spring months, and not meant for harsh winter conditions.

Winter (+10°and lower) sleeping bags rated at this temperature are constructed with extra insulation and will keep you warm through the coldest of nights. Although if the conditions you’re camping in are below 10 degrees, then you may want to consider adding extra layers and pads for guaranteed protection from the cold.

Winter Sleeping Bag

3-Season (+10°to +35°) sleeping bags are the most versatile in their ability to keep you comfortable during a variety of weather conditions. These sleeping bags are the most useful during mild spring and fall nights when the weather is cool but not cold.

Naturally, we will be focusing on summer (+35°and higher) sleeping bags in this article, but keep in mind that the temperature range we mentioned was just a benchmark. Plenty of summer sleeping bags come with a temperature rating above or under the benchmark. In the end, it all depends on your individual needs.

Weight

How much your sleeping bag weighs is something you need to think about if you are planning on going on a backpacking trip, where you’ll be carrying it in your sack all day. Most sleeping bags weigh in at around 1-4 pounds, depending on the construction and insulation.

Sleeping Bag Weight

Some sleeping bags are more compact than others, making them easier to fit into your backpack. Think about what kind of camping trip you are going to be taking, and take into consideration how much your sleeping bag is going to weigh you down before you choose the right bag for you.

Shape

Choosing the correct shape of the bag for you is a critical step when buying a sleeping bag. If your sleeping bag is too big or has too much room, you could be sacrificing warmth and insulation. On the other hand, if your sleeping bag is too small or tight, it could lead to an uncomfortable and cramped night’s sleep.

Sleeping bags come in four general shapes: mummy, rectangular, barrel, and double-wide. Let’s start with the mummy bags.

Mummy Sleeping Bag

Named after the shape of a tightly wrapped mummy, mummy sleeping bags are often narrower at the shoulders and hips to provide optimal insulation. These bags are more restrictive and may not be comfortable for all types of campers’ body sizes and sleeping preferences. The upside to mummy shaped sleeping bags is that they are the most lightweight and compact, making them ideal for backpackers.

The most traditional shape for sleeping bags is rectangular, and it is often the most comfortable. These sleeping bags don’t offer the most warmth and insulation but are praised for their comfort and versatility.

Most campers don’t have a problem fitting into this sleeping bag, and they work for taller and shorter campers alike. If you’re looking for a roomy option, or are interested in joining multiple sleeping bags to create room for more than one person, the rectangular shape is a great option.

Rectangular Sleeping Bag

Barrel sleeping bags are similar to the rectangular shaped ones but boast a more tapered design. Barrel-shaped bags are somewhere in between a mummy and rectangular shape and give you warmth and insulation without sacrificing roominess. Barrel-shaped sleeping bags are beloved by larger-framed campers who find the mummy sleeping bags too restricting.

Double-wide sleeping bags are made for two campers to sleep in together. This shape is ideal for couples or families. Double-wides can also be created by combining two rectangular shaped sleeping bags with opposite facing zippers. Most sleeping bags that are sold as double-wides come apart into two individual bags, making this shape versatile for a multitude of camping needs.

Additional Features

While most sleeping bags come with a variety of additional features to ensure a comfortable sleep, some common features are particularly useful when searching for the perfect summer sleeping bag.

Sleeping Bag Additional Features

First, you’ll want to pay attention to the shell and lining. It’s important to make sure that your sleeping bag’s lining is water resistant. Most sleeping bags come with a standard lining made of synthetic materials such as polyester or nylon.

Higher-quality sleeping bags come with shells treated with a durable water repellent finish or DWR. These DWR-finished sleeping bags are the best option for repelling water and keeping you and your sleeping bag dry throughout the night.

You’ll also need to consider the stash pockets. Some sleeping bags feature internal pockets that are perfect for keeping small items close at hand such as cell phones, glasses, keys, books, etc. Stash pockets are great for items you want to ensure won’t get wet, and keeping valuable items like jewelry and money close-by throughout the night.

Pillows aren’t something you often think about when camping in a sleeping bag. Since sleeping bags don’t come with pillows, it’s a great idea to look for one with a built-in pillow pocket. This pillow pocket allows you to stuff clothing or a blanket into it to create a makeshift pillow that will support your head and neck while you are sleeping. You can also purchase a specially made camping pillow that will fit into most pillow pockets.

Sleeping Bag With Pillow

While most sleeping bags come with a built-in liner, if you’re looking to keep your sleeping bag extra spotless and add in some additional warmth and comfort, a sleeping bag liner is a great option for you. These liners slip into your sleeping bag and act as an extra layer of warmth. They are great for turning a sleeping bag into a versatile piece of camping gear that works in a variety of temperatures and climates.

Durability

The durability of a sleeping bag can be measured based on the materials they are made of. You’ll want to go with nylon if you’re looking for a tough and rugged option—just make sure it’s DWR treated.

The insulation also plays a role in determining the durability of a sleeping bag to a degree. Goose down is more volatile since you run the risk of ruining the insulation if you compress it too often or wash it roughly, whereas synthetic insulation is easier to maintain.

Whatever type of material or insulation you end up going for, however, the golden rule is that a good quality sleeping bag can last you for years if you take the time to care for it properly.

Sleeping Bag Durability

If you’re using your sleeping bag in a tent, you don’t have to worry about it touching the ground. But if you plan on using your sleeping bag to sleep out in the open, it’s important that you use a sleeping pad to protect your sleeping bag from the damp and dirty ground.

Crashing in your sleeping bag after a long day of hiking can seem tempting, but the dirt and oils from your clothes and skin can ruin your sleeping bag’s quality and insulation over time—especially if it’s goose down. It’s important to take the extra step to change out of your muddy and dirty clothes, and wipe off any sweat, sunscreen or bug spray that is lingering on your skin.

When your sleeping bag starts to smell or get grimy after a couple of uses, it’s time to wash it. Washing your sleeping bag is essential for keeping it in tip-top shape. If it’s not too dirty, you can simply spot-wash it with cool water and let it air dry.

But if it’s due for a full bath, then hand-washing your sleeping bag in a tub of cool or warm water and gentle soap is the best option. Letting it soak for an hour in the water, and then drying it on low-heat or air-drying it will ensure that your sleeping bag stays fresh for a long time.

You should be airing out your sleeping bag every day you use it to avoid excess moisture from ruining it. To do this, turn your sleeping inside out and hang it in the sunlight. Although it’s important not to leave it in direct sunlight for more than a couple of hours, as the UV rays will destroy the sleeping bag’s fabric and insulation.

When you’re finished with your camping trip, and it’s time to store your sleeping bag away you should remember to let it breathe. Never store sleeping bags compressed or folded tightly. Air the sleeping bag out before storing it, and fold it loosely to avoid long-term damage. Cotton, mesh, or other breathable sacks are a great place to keep your sleeping bag to avoid moisture and mildew.

Without further ado, here they are:

Slumberjack Lil Scout Sleeping Bag

Price: Approx. $41Lil Scout

Weight: 2.2 pounds

Dimensions: 2 x 16 x 8 inches

Specific features: 100% Polyester lining, built-in pillow pocket, interior pocket, a snug hood, two-layer off-set construction to prevent cold spots, Slumberloft Synthetic insulation, draft tube zipper, 40°F temperature rating, trapezoidal foot box

Best use: For children, indoors, outdoors, warm summer nights

The Slumberjack Lil Scout Sleeping Bag is made for children under the height of 55 inches. It’s perfect for frequent campers or scouts who go on camping or backpacking trips during warmer months. Weighing only 2.2 pounds, it’s a great option for kids to carry around all day. Although it is light, the Slumberjack tends to be a bit bulkier, making it harder to stuff into smaller backpacks.

The zipper is strong enough to survive the pulls of rowdy children, but should still be handled with care to prevent ripping. Even though this sleeping bag is meant for kids, it boasts a lot of the same great features that adult sleeping bags do. Including a high-quality and durable Slumberloft Synthetic insulation, a flip over hood with space for a pillow, and interior stash pockets.

The rectangular shape allows for more room so children can wiggle about while sleeping, while still being tapered enough to keep them warm. The 40°F temperature rating is perfect for camping in the summer months, keeping your kids cool in the heat. The Slumberjack is a great summer sleeping bag for beginning campers who want to explore the great outdoors.

PROS:

  • Lightweight, easy for children to carry
  • Durable
  • Comes with a big hood
  • Comes with interior stashing pockets
  • Spacious but warm
 CONS:

  • A bit bulky
  • The zippers need to be handled with care

Big Agnes Spike Lake 15 Sleeping Bag

Price: $200 – $210Big Agnes - Spike Lake 15

Weight: 4 pounds

Dimensions: 25 x 10 x 10 inches

Specific features: DownTek insulation, no-draft technology, exterior loops, fitted hood, 15°F temperature rating

Best use: Summer camping with cooler nights, outdoors

The Big Agnes Spike Lake 15 Sleeping Bag is a mummy shaped sleeping bag that has an impressive 15°F temperature rating. It’s a very versatile sleeping bag that will keep you as cool on summer nights as it will warm on winter nights. This is mostly thanks to its 600-fill DownTek water-repellent insulation and water resistant shell.

The insulation is made with natural goose-down and treated to ensure a waterproof sleeping bag. Because of its insulation, the Big Agnes is in fact big. It weighs 4 pounds, one of the heavier sleeping bags we’ve listed here. This means it may not be suitable for longer backpacking trips, as its ability to fold down into a lightweight, compact package is nonexistent. But what you lose in compactness you gain in comfort and extra features.

The Big Agnes comes with a collar and zipper that covers your body from the chin down, wrapping you up in a warm cocoon of comfort. It also has nifty exterior loops that make airing out and drying your sleeping bag a whole lot easier.

PROS:

  • Very warm thanks to the 600-fill DownTek insulation
  • Waterproof thanks to the treated shell and goose down
  • Comes with a neck baffle
  • Easy to air out and dry thanks to the exterior loops
 CONS:

  • Bulky, even when packed down
  • Heavy

Related: If you’ve got a small backpack with little space to spare for a sleeping bag as bulky as the Big Agnes and yet you’re not willing to give up on the comfort it offers either, this Big Agnes Super Light Girdle should be able to offer assistance. It compresses the sleeping bag down. Since down is more compressible than synthetic, this should help quite a bit.

Nemo Tango Solo 30 Sleep System

Price: Approx. $259Nemo Tango Solo 30

Weight: 2.58 pounds

Dimensions: 9.9 x 9.9 x 17.5 inches

Specific features: Works with any 25-inch sleeping pad, backless design, 30°F temperature rating, down fill insulation

Best use: Under-the-stars camping, backpacking

The Nemo Tango Solo 30 Sleep System is a down sleeping bag with 30°F temperature rating, making it perfect for warmer weather camping trips. It’s also rather lightweight for being a down-filled insulated sleeping bag, weighing in at 2.58 pounds. This is because of its backless design.

Not having any down on the backside of the Nemo Tango may seem odd to some campers who are used to having all-over cushion and insulation. But this feature allows for the sleeping bag to be more lightweight and recognizes the issue of down losing its insulation ability when compressed. Just slip any standard 25-inch sleeping pad under the Nemo, and you’ll be sure to sleep soundly through the night.

Also because of the sleeping pad, this is a great option for those campers who enjoy sleeping under the stars. The sleeping pad protects your sleeping bag from dirt and moisture that can destroy its shell.

PROS:

  • The unique backless design makes it lightweight
  • Goes great with a sleeping pad
  • Won’t lose its insulation ability when compressed
  • Warm
 CONS:

  • A bit too spacious for one person, leaving a lot of room for air pockets to form

Related: You can crank the comfort levels up even more by putting up this Therm-a-Rest Slacker Snuggler somewhere near your camp. This hammock is also good for two people. You can snuggle in the hammock during the day then move on to snuggle in the sleeping bag as night falls.

It can easily fit campers up to 6’6 feet tall and claims to have the longest and widest mummy shaped bag on the market.

Its insulation isn’t too shabby either, with a 60°F temperature rating the Tough Outdoors bag is a versatile 3-season sleeping bag—although you might want to stick to the summers with this one if you tend to get cold easily.

It comes with a soft-woven inner liner, durable and ripstop waterproof shell, a reinforced zipper and a cinch around the face to block windy drafts from coming in at night.

It comes with a contoured hood to give you extra support and comfort, as well as a chest baffle that will keep you cozy and warm as you sleep.

This sleeping bag is quite lightweight and is available at an affordable price, which makes it great for casual camping trips in warm climates. This sleeping bag will ensure a great night’s sleep for anybody who uses it.

It comes with a zipper closure and therein lies the main problem. The zipper is not non-snag, so you’ll have to treat it carefully, or you’ll be in for one very frustrating trip.

PROS:

  • Affordable price
  • Comfortable thanks to the contoured hood and chest baffle
  • Lightweight
 CONS:

  • Not very warm
  • The zipper is a bit difficult to handle

Badlands Cinder Synthetic Sleeping Bag

Price: Approx. $155Badlands Cinder

Weight: 2.6 pounds

Dimensions: 9 x 9 x 13.5 inches

Specific features: Lifetime warranty, DR resistant coating, draft collar, double-insulated foot box, synthetic, 35°F temperature rating

Best use: Camping, hunting, hiking

The Badlands Cinder Synthetic Sleeping Bag is a serious sleeping bag made with double insulation and a 35°F temperature rating. It’s perfect for all camping conditions but is specially designed with hunters in mind.

It’s very waterproof with a DR resistant coating and can withstand the rainiest of nights. It also features great additions like a draft collar and reversible zippers.

You’d think that the fact that it’s made of synthetic material would make it lightweight and compact, but that’s not the case with this one. Perhaps due to its solid construction and great insulation, it’s a bit bulky at 2.6 inches, and might not be an ideal sleeping bag for compressing down into a lightweight pack.

Although it does come with the Badlands’ Unconditional lifetime warranty, so you don’t have to worry about quality when it comes to this sleeping bag. But if you find it isn’t the right bag for you, Badlands will happily replace it.

PROS:

  • Very warm thanks to the double insulation
  • Waterproof thanks to the DR coating
  • Nonsnag, reversible zippers
  • Comes with a lifetime warranty
 CONS:

  • A bit bulky and heavy

Related: If you’re on a hunting trip, you might need to camp out for several nights depending on how the hunt goes. You’ll need a versatile stove to accommodate your changing needs. One of these Etekcity Ultralight Camping Stoves would be the perfect solution for that. It’s collapsible, and it comes with its own portable carrying case.

RevalCamp Lightweight Sleeping Bag

Price: Approx. $28Lightweight Sleeping Bag

Dimensions: 30 x 71 inches

Best use: Outdoor or indoor, summer camping

It’s a surprisingly long, traditionally rectangle shaped bag that can even accommodate campers up to 6’5 in height. You might think that such a long sleeping bag would definitely be on the bulky side, but that’s not the case at all. It compresses down to about 7 x 7 x 7 inches, making it ideal for fitting into small spaces when the room is tight.

Because of its ability to turn into a two-person bag by zipping two bags together, the RevalCamp sleeping bag is a great option for couples and families who want to snuggle in the great outdoors.

This sleeping bag is versatile for everything from camping to hiking, to sleepovers. The fabric feels a bit thin and flimsy, though, so you might want to treat it a bit more carefully.

PROS:

  • Great for tall campers
  • Can be zipped together and turned into a 2-person bag
  • Packs down small
 CONS:

  • The fabric feels a bit thin and flimsy

Related: No matter what kind of camping or hiking trips you’re going on, never enter the woods without having one of these Etekcity Portable LED Camping Lanterns with you. You never know what kind of danger might be waiting for you in the dark when you’re out there in the great wilderness.

    I bought the Slumberjack Lil Scout 40 Sleeping Bag 2015 for my 3 year old. He must think it’s really comfortable because the little guy falls right to sleep in minutes after getting in. The only issue I’ve really had with it is the zipper. The zipper can get caught up a little bit if you’re not careful.

  • Bradley Page

    Hi Chris! Thanks for your experience with the Slumberjack! Yeah sometimes, I do find myself fumbling with zippers but that bag is so awesome, right?

  • Kevin Pavlik

    In the warmer weather, I use the Big Agnes — Spike Lake 15 Sleeping Bag. It’s warm and light and I sleep like a log when I use it. I haven’t yet used it in the colder temperatures yet (like, down to 15 degrees or somewhere around there.) Does anyone have any experience using this bag in the colder temperatures?

  • Bradley Page

    Hi Kevin, the good news is that the Big Agnes has a 15° temperature rating, making it suitable for use in summertime and winter. Always check the temperature rating of sleeping bags to ensure that you’re getting what’s suitable for the seasons. All in all, the Big Agnes is a stellar product and very heavy-duty – lasting for a number of years, that’s for sure.
