Best Summer Sleeping Bag

What You Must Know
There’s nothing like sleeping under the stars on a warm summer night!
The smell of the forest and the immensity of the Universe above make this experience one you want to repeat. Still, without the best summer sleeping bag, things can go downhill fast when you start feeling the cold creeping towards your bones!
How to Choose the Best Summer Sleeping Bag
The sleeping bag is the most important sleeping equipment you ought to have on you whether you go car camping or hiking.
This piece of equipment is designed to shield you from the cold air of the night and the humidity of the ground, using your own body heat. However, it is also breathable, so you won’t get too hot and disturb your sleep.
Now, most sleeping bags for summer time are lightweight and low-cost, but you should still keep a few characteristics in mind when you make the choice. Below I listed some of the most important ones, so make sure to study them intently before going shopping.
Filling or Insulation
Each sleeping bag uses a type of filling to provide insulation from the elements and to keep you comfortable. For summer models, the most common fillings are synthetic or down (fluffy feathers).
Down insulation is better at keeping the cold away than synthetic materials, plus it packs smaller (important for hikers and backpackers). Still, it’s not as durable (especially in humid environments) and the costs are usually high.
On the other hand, synthetic insulation (polyester fibers) doesn’t absorb moisture and continues to keep you warm and toasty even in high-humidity environments. It’s also more affordable, which is why many campers prefer this type of filling.
At the end of the day, the choice of insulation is highly personal as both will provide you with comfort.
For a summer sleeping bag, the outer layer should be breathable (to avoid any condensation on the inside), durable (resistance to tearing), and repel water. This way, you can use the bag outside the tent without worrying that the first twig will rip the cover.
This feature is important for any sleeping bag if you want to make the trip on foot. If you only go car camping, weight doesn’t matter as much.
Basically, summer sleeping bags are lighter and pack smaller than 3-season or winter models. This happens due to the reduced amount of insulation, but it’s also an indicator of the quality of the filling material.
High-quality insulation means the bag is lightweight (due to the warmth-to-weight ratio), while a heavier/bulkier bag means more insulation had to be used to provide the same level of warmth.
Most manufacturers use the EN (European Norm) 13537 standard rating to show the level of comfort the bag will provide at certain temperatures. This means the bag was tested to identify the recommended levels of temperature.
The EN 13537 standard has four ratings:
- Extreme temperature (minimum temperature at which a regular female can survive for 6 hours);
- Lower limit (how much cold the bag can really withstand);
- Comfort temperature (minimum temperature at which you’ll be comfortable);
- Maximum temperature (overheating limit).
Keep in mind: Some manufacturers don’t use EN ratings but use their own tests. However, the results can be inaccurate, so it’s best to only buy from brands you trust.
Style & Size
As you go through a plethora of products, you’ll notice several styles, but the most common are these:
- Mummy – This type of bag wraps around the body, making you into a mummy, with only the face out. In my opinion, this design is perfect in any situation as it keeps you warm from head to toes.
- Rectangular – They are rectangular in shape, with plenty of room to move around. Since they don’t have a hoodie, the insulation properties are not as great, so I only recommend them for hot summer nights.
- Wearable – As you can imagine, this one is more a fluffy suit you put on than a sleeping bag. It is great for those cold and humid mornings, but it doesn’t offer the comfort of a blanket.
I am a strong supporter of the mummy sleeping bag because I find it to be the most comforting and accommodating. However, when it comes to the best summer sleeping bag, I find the rectangular design to be more suited because it’s more breathable.
In terms of size, sleeping bags come in all sizes (unisex, male, and female), so make sure you buy one that fits your needs.

Designed to keep you warm during three out of four seasons, the MalloMe sleeping bag is lightweight, but I find it a bulky. Still, it’s easy to hook it up to your backpack, due to its compression sack specially engineered to keep the bag under control.
This is a rectangular sleeping bag that comes in a wide range of colors and sizes. The individual design (there’s also a twin model for two people) is 32-inch wide, which is over the standard size, to give you more space inside.
The bag is equipped with enough polyester filling to withhold temperatures from 35° to 85° F. so you can use it even when it’s a bit chilly outside. In the summer, you can let the feet breathe by simply opening the bag at the bottom.
The cover features a 6-sided 100% polyester hexagonal weave that’s perfect for durability and water-repelling. Moreover, the no-snag double-sided zipper is perfect for easy access in and out of the bag. There’s also a Velcro securing strap to make sure the zipper doesn’t open by accident while you sleep.

- Durable and easy-to-use zippers
- A wide range of colors and sizes
- Rectangular shape
- Comes with compression bag
- Easy to clean
- Soft and comfortable material
- A bit bulky
- Material is slick
- Better for cool summer nights
The ECOOPRO sleeping bag is one of my favorites because, when it’s compressed, it is a tiny, lightweight package, but when unfolded, it is comfy, durable, and breathable (ideal features for a sleeping bag!).
Since it’s so tiny when packed (11-inch in height and 1.7lbs), it can be easily fit inside a backpack or hooked on the outside without you feeling any added weight. Still, you may want to practice folding it before you go on a trip because the compression sack is a bit small and it takes a bit to get used to the entire operation.
This is a rectangular sleeping bag, which makes it perfect for summer camping. It is waterproof, due to the outer 400 T nylon layer, and comfy on the inside, due to the polyester filling and premium TC cotton lining. This combination of materials will keep you warm and toasty in temperatures varying from 48 to 59° F.
- Waterproof design
- Comfortable filling
- Compresses into a tiny package
- The liner can be removed when it’s hot outside
- Perfect for kids, teens, and adults
- Designed for three seasons
- Perfect for summer hiking or biking trips
- Comes with compression sack
- Durable zippers
- Velcro strap to secure the zipper

- A bit tricky to fold & compress
This is an adult-sized bag (for people up to 5 feet 11 inches) with 100% polyester filling that can be used in temperatures between 40° and 60° F. The cover and liner are also polyester, but they feel nice to touch and provide a soft, comfy surface.
If you’re worrying that the polyester lining will make you sweat, you can relax. The fabric is breathable, and the rectangular design allows for perfect temperature regulation. This means you’ll be warm but won’t sweat while inside the bag since the temperature will be just right.
I know you’ll appreciate the ZipPlow system, that pushes fabric away from the zippers to prevent any snagging. It also uses a Roll Control system, so it’s easier to pack by one person. Finally, the bag has a comfort cuff, which is a piece of plush material right at the edge, so you won’t feel the polyester cover on your face.
- Durable design
- Extremely soft
- Keeps you warm
- Zipper is smooth
- The ZipPlow system works wonders
- Built-in ties that make rolling up easier
- The cover is slick so water slides rights off

- The storage bag is really tight
It fits a 6 feet person (75″x33″) and can be used as a quilt if you place it with the cover side on the grass. The cover is designed with durable 210T polyester ripstop fabric, which is waterproof and durable, so you shouldn’t have any problems. Still, I don’t recommend using the bag on rough terrain with rocks and other rough surfaces.
On the inside, you’ll find a soft flannel lining that feels nice against the skin and keeps you from sweating during the night. The bag is filled with high-density rebounded hollow cotton fibers which create a fluffy look and increases breathability.
It keeps you extra-warm due to the windproof layer that prevents any cold air from getting inside and drawstring closure that allows for a tight fitting around the neck. So, even though it’s rectangular in shape, you can adjust the closure to be as wide as you want.

- Withstands temperatures between

Designed with durable 170T polyester cover that repels water and keeps cold air away from your feet, this rectangular sleeping bag is perfect for summer hiking trips!
I like that it’s lightweight (only 34oz) and the fact that it packs tightly in a small package that can be easily hooked on your backpack or bike. It measures 75″ in length and 30″ in width, so it will easily fit a fully-grown adult.
On the inside, the bag is equipped with 200 GSM hollow fiber filling, which means it will keep you warm and comfy in 50°F temperatures. The producer says that, in emergency situations, you can also use it in 25°F weather, but I wouldn’t recommend it since this is a summer sleeping bag.

- Soft and warm lining
- Rectangular shape
- Compact when folded
- Comes with carrying case
- Perfect for summer hiking trips

If I were to recommend a product out of the listed five, I think the ECOOPRO Warm Weather Sleeping Bag would be my first choice. It is lightweight, it packs small so it’s great for backpacking, and it fits kids and adults.
Overall, the secret to finding the best summer sleeping bag stands in choosing the product that fits your needs. For instance, if you usually go car camping, you can spoil yourself with a big, fluffy sleeping bag that provides plenty of space. On the other hand, as a hiker, you’ll need to be a lot more concerned about weight and size.
