Best Summer Sleeping Bag - Reviews

Ecoopro designed this sleeping bag for extended use in the summer. It is durable, simple to use, customizable, and compact when compressed.


The sleeping bag is 30” wide and 6.9’ long. The rectangular design guarantees plenty of room for restless sleepers, as well as great air circulation and improved breathability in warm weather.

The premium TC cotton maintains a decent temperature when using the sleeping bag in temperatures of 48 to 59 degrees F.

The outer shell is as rugged as they come. It’s weatherproof thanks to its enhanced water and wind resistance. The smooth zip closure makes it easy to use the bag while also helping with temperature regulation.

You may also want to consider the Ecoopro sleeping bag if you prefer lightweight camping equipment. When compressed, the sleeping bag is just 11” tall and 1.7 pounds – clearly a weight that any backpacker can handle.

But, what makes this sleeping bag even more special is the removable liner. This feature allows you to use the sleeping bag even when it’s very hot out.


  • Fits tall people
  • Spacious design
  • Removable lining
  • Waterproof outer shell


  • Only 2 available colors
  • Zipper snagging might be a problem

Are you planning on backpacking in the middle of the year? If summer camping is your thing, then Redcamp’s sleeping bags might be just the thing for you. The lightweight is one of the best things about this sleeping bag. Of course, the price tag, rugged zippers, and level of comfort add even more value.


If you’re over 6’ tall, this may be the sleeping bag for you. It weighs just 1.5 lbs. and it comes with a compression sack that makes it easy to pack and carry. The lining and the design of the sleeping bag are made for comfort in the high 70s, which makes it great for use in the summer.

The soft lining is not removable. However, a cool feature is the reverse 2-way zipper. You can use this to attach two Redcamp sleeping bags together and share the extra room with someone else. It’s a good idea for couples or families since there’s enough room in two bags for two adults and a child.

The outer shell is water resistant but not waterproof. Therefore, it may not be ideal for camping out in the open where you’re bound to pick up moisture on the ground overnight.

The rectangular design leaves plenty of room on the sides for your arms and legs. However, you can also make use of the drawstrings to adjust the tightness and create a snugger environment. The interior stuff pocket is great for storing your gadgets and providing some additional protection from the elements.


  • Budget-friendly
  • Spacious rectangular design
  • Can be zipped together with another Redcamp bag
  • Comfortable up to the high 70s


  • Not waterproof

This 3-season envelope sleeping bag is spacious and available in 5 colors, and it comes with a great compression sack for easy transportation. It’s affordable to begin with and its comfort and protection features make it worth every penny. Furthermore, the lightweight design and smooth lining also allow you to use the sleeping bag as a cool summer quilt.


Are you in the market for a sleeping bag that’s comfortable from the high 50s to the high 70s? If so, the Besteam might be able to satisfy that need. Although rated for 3 seasons, this sleeping bag performs best during the summer.

It’s a single sleeping bag that measures 30” in width and 6.25’ in length. It’s not exactly the biggest sleeping bag on the market but it will do for the average camper. Also worth noting is that it can be compressed to a very small size.

The quality/price ratio is very good. Standard TC cotton filling is used to protect from the night chill without overheating. The lining is silky and breathable which helps keep you cool on hot summer nights. However, the sleeping bag is thin overall.

Without a sleeping pad, the cool summer breeze might hit you hard. So be sure to prepare. Also know that you can zip two bags together. The rectangular design makes this easy as you simply have to unzip two bags all the way, place them on top of each other, and zip them together.

Due to the quality of the zippers and seams, you won’t lose any warmth by doing this.


  • Comfortable to the high 70s
  • Thin and ultralight sleeping bag
  • Compression sack included
  • 2-way zippers


  • May be too thin for cold nights
  • Average waterproofing

This sleeping bag might be the top choice for campers shopping on a tight budget. Its rated comfort range is between 59 and 68 degrees.


The sleeping bag is filled with 100 GSM filling. The light filling offers good breathability but it’ll get too hot when the outside temperature is in the high 70s. Is there a problem if you go camping in the height of summer? The solution is very simple. Just don’t sleep in a sleeping bag (any sleeping bag) when it’s too hot out.

The outer shell is made of 190T ripstop polyester. It is durable and offers some protection against the elements. However, it requires an aftermarket waterproofing treatment as 190T is just water resistant. This is, of course, completely optional if you only sleep in a tent.

The sleeping bag comes in a compression sack. The total weight of the bag and the sack is 1.65 lbs. which is close to nothing for an avid backpacker.

Although the sleeping bag is rated down to 50° F, you’re going to need warm clothes and perhaps a good sleeping pad for that.


  • Spacious envelope design
  • Decent filling
  • Very affordable
  • Compact when compressed


  • Not waterproof

If you’re looking for something rugged, snug, and friendly to tall individuals, Tough Outdoors might have you covered. Sure, a mummy-style sleeping bag is not everyone’s first choice for summer camping but the air circulation in this model is far superior to what you would expect.


The design is for 3 seasons. However, the filling is going to make it too hot when the temperature inside the tent is in the 70s. It’s perhaps best suited for early or late summer conditions. As mentioned, don’t sleep in a sleeping bag when it’s too hot.

The Tough Outdoors sleeping bag should accommodate adults who are up to 6’6” tall comfortably. However, the 32” width is only around the shoulders. As you move down towards the base, the width is gradually reduced because of the mummy-style design.

This means that in terms of space, there’s not a lot to work with. But there is a positive side to this too. Because of the mummy-style design, this Tough Outdoors sleeping bag has better warmth retention properties.

The air circulation and rugged outer shell really allow you to use the sleeping bag in the spring and fall as well, as opposed to a strictly summer sleeping bag.

In terms of price, this is not the cheapest model. However, it’s not as expensive as you may think either, especially when you consider its 3-season versatility. If you don’t have a problem with a snug fit during the summer, you may just have to give this one a try.


  • Rugged outer shell
  • 3-season sleeping bag
  • Fits people up to 6’6” tall
  • Compression sack included


  • Less spacious
