Planning a summer trek to hike new trails and sleep under the stars? Don’t go anywhere without your trusty summer sleeping bag! To stay cool and dry on the trail without weighing down your pack, it’s essential to select the best summer sleeping bag for backpacking to give you the rest you require.

Not sure how to choose the best summer sleeping bag for backpacking? Here’s what you need to know about picking a summer sleeping bag, including the top 5 options you’ll want to consider for your next trek.

The Buyer’s Guide to Choosing The Best Summer Sleeping Bag for Backpacking

If you’re not sure what to look for when picking out the best summer sleeping bag for backpacking, you’ve come to the right place. Check out the key features you’re going to want to keep an eye out for below.

Identify Your Campsite

Your campsite is an important factor to take into consideration when picking out the best summer sleeping bag for backpacking. You need to identify where you intend to set up camp and your usage needs for your sleeping bag before you can choose the one that works best for you.

For example, check out the expected weather conditions in the region you’re going to be backpacking and camping in, the shelters around, and how long you’ll be sleeping in the great outdoors.

You’ll also want to consider factors such as the altitude and wind in the area of your campsite(s). That way, you’ll be able to decide which summer backpacking sleeping bag has the features you need to protect you from certain kinds of elements and hold up against the type of environment you’ll be camping in.

Temperature Ratings

The vast majority of sleeping bags available sport some kind of a temperature rating. Summer sleeping bags are typically rated for 35 degrees Fahrenheit and up. You’ll want to purchase a summer sleeping bag with temperature ratings a little bit under the minimum temperature you expect to be camping in.

You’ll find it much less complicated to just unzip your sleeping bag if temperatures get a bit too balmy rather than try to get warmer if a chilly wind sets in.

Consider Liners

Even if you’re going to be camping in summer weather, it’s always a good idea to be prepared for a cool night at the campsite just the same. You can easily add a sleeping bag liner for extra warmth if needed. Liners are a great way to use your summer sleeping bags in a variety of climates and extend the multi-use function of your gear.

If you’re going to be backpacking in a region where the weather changes on a dime or is prone to variance, you’ll definitely want to consider having a sleeping bag liner on hand, just in case. There are liners available for just about any type of sleeping bag, in materials such as cotton, silk, fleece, and synthetic fabrics with great moisture wicking properties.

Does the Sleeping Bag Provide Sufficient Insulation?

When selecting the best summer sleeping bag for backpacking, you’ll definitely want to consider the amount of insulation it provides compared with your usage needs. Sleeping bags manufactured from synthetic fibers typically feature a solid range of textures and shapes that are soft and compact enough to make for easy packing.

Synthetic fibers provide quality insulation even when they get wet, which is a great thing if you run into summer rains.

However, synthetic sleeping bags are also a lot heavier and take up more space than standard sleeping bags featuring down insulation do. Besides this, synthetic material doesn’t usually last as long as down. That said, synthetics are considerably easier on the wallet than goose down, so this is another element to take into account as well.

When it comes to the best summer sleeping bag for backpacking made with goose down, you’ll enjoy exceptional insulation that truly stands the test of time. Goose down sleeping bags are a solid investment, so if you care for them well they really will last you forever.

Sleeping bags made with goose down are also highly compact so you can fit them into your gear with ease.

The only major downside with goose down is the fact that it doesn’t wick moisture at all and completely foregoes its insulating properties when it becomes wet. The good news is, some manufacturers opt to incorporate waterproof shells for goose down sleeping bags to solve this conundrum.

You can keep your goose down sleeping bag in a waterproof bag when on the road to avoid it getting wet if you come across some showers. Goose down sleeping bags are more expensive than synthetics, but their longevity of use is well worth it.

What Is Your Preferred Sleeping Bag Shape?

You can purchase the best summer sleeping bag for backpacking in a range of shapes and sizes, so it partly comes down to a matter of personal preference and partly to functionality. The 3 main types of sleeping bag shapes are mummy sleeping bags, rectangular sleeping bags, and semi-rectangular sleeping bags.

Mummy sleeping bags are narrower and made to fit nice and tight around the body for extra insulation. Some mummy sleeping bags include an insulated hood to keep your head even warmer in cooler conditions.

You can close the insulated hood if you so desire or leave it open if it’s too warm outside. While it might not some like this would be the case, mummies are actually the most lightweight summer sleeping bag option.

If you don’t care about the narrower fit of a mummy sleeping bag, this type will save you plenty of space in your gear and won’t weigh you down. Plus, if you run into cooler temperatures at night, the bag will keep you warm and insulated.

Rectangular sleeping bags are the traditional option, offering you plenty of freedom of movement to sleep in. We would note that the rectangular design is not quite as insulating as the mummy variety, but if you’re going to be backpacking in strictly balmy temperatures, that will work to your advantage.

The majority of rectangular sleeping bags sport double zippers so you can transition your sleeping bag into a cozy blanket.

Semi-rectangular sleeping bags are a new selection on the market, meant to offer a happy medium to users between the mummy and rectangular design. You’ll have less space to sleep in, but you’ll also enjoy better insulation. If you like some of the qualities of mummies but feel they don’t offer enough space to move, you might like the compromise of a semi-rectangular sleeping bag.
