Sleeping bags are an essential part of any camping trip. Not only do they provide you with a comfy night’s sleep, they also act as an extra layer of protection between you and the elements of nature. When most people think of sleeping bags, they think of heavy, down bags that are made to keep you warm on cold winter nights. While many sleeping bags are constructed with warmth 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 to accommodate your summer camping trips, look no farther. This guide will help you choose the best summer sleeping bag that will keep you sweat-free during your next summer camping trip.

Below you will find tips on what to look for when choosing your next sleeping bag, how to care for your sleeping bag once you’ve bought it, and a list of the top summer sleeping bag choices available. It can be easy to avoid restless nights and sweaty mornings with a versatile, temperature rated sleeping bag. Ensure that your next summer trip will leave you with cool and comfortable memories with these best sleeping bag options.

What to Look for In a Sleeping Bag

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.

Summer 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.

  • Synthetic: This 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.
  • Goose-Down Insulation: This 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. 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 there are many factors that 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) – These 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.
  • 3-Season (+10°to +35°) – Multi-season 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.

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. 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 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.

Below are some of the most common sleeping bag shapes that you can consider.

  • Mummy: Named after the shape of a tightly wrapped mummy, these 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 are they are the most lightweight and compact, making them ideal for backpackers.
  • Rectangular: This is the most traditional shape for sleeping bags, and often the most comfortable. Theses 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 shaped 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.
  • Barrel: These 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 built campers who find the mummy sleeping bags too restricting.
  • Double-wide: Double-wide sleeping bags are made for two campers to sleep in together. This shape is ideal for couples or families who prefer sleeping together. 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 a part 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, here are some common features that are particularly useful when searching for the perfect summer sleeping bag.

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.

Stash Pocket

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 safe and close-by throughout the night.

Pillow Pocket

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 make shift pillow that will support your head and neck while you sleeping. You can also purchase a specially made camping pillow that will fit into most pillow pockets.

Sleeping Bag Liner

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 a temperatures and climates.

How to Care for Your Sleeping Bag

A good quality sleeping bag can last you for years if you take the time to care for it properly. Follow these steps below to ensure that your sleeping bag will last you for many camping trips, and keep its quality and comfort season after season.

Keep it Dry and Off the Ground

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.

Go to Bed Clean

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. 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.

Hand Wash and Dry on Low Heat

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.

Air it Out

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 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.

Store Properly

When you’re finished with your camping trip, and it’s time to store your sleeping bag away you should remember to let it breath. 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.

    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.
