👉 The key facts from this guide
- Choosing the right sleeping bag is essential for a restful night outdoors. Size and weight play an important role, especially when you're backpacking.
- There are different types of sleeping bags designed for various needs and weather conditions. For people who move a lot during sleep, a spacious rectangular sleeping bag might be more suitable than a classic mummy bag.
- In winter, you'll need a well-insulated sleeping bag that can withstand sub-zero temperatures. In summer, the sleeping bag should be breathable to avoid excessive sweating.
- There are both single and double sleeping bags. Some recommended models for individuals are the Kelty Galactic 30, the Sea to Summit Traveler TrI, and the Coleman Pacific, as well as the Big Agnes Dream Island 15 and the Coleman Tandem 3-in-1 Double Sleeping Bag for two people.
- Some sleeping bags, such as the Marmot Nanowave 45, are specifically designed for hiking, cycling, and kayaking tours as they are lightweight and compressible.
- There are also special winter sleeping bags, such as the Carinthia Defence 6 and the Mammut Protect -18 °C, which are designed for extremely low temperatures.
The right sleeping bag is essential for a restful night. Because those who sleep comfortably are full of energy.
This applies to all people who sleep outside, whether it's a rooftop tent, icy winter camp, or a warm summer sky.
There is nothing worse than waking up at night from cold or with icy feet.
And it is just as unpleasant to sweat through the night in a cheap plastic bag.
But when it comes to choosing the best sleeping bag for camping, there are many options to choose from.
Why you shouldn't just take any sleeping bag
Size and weight are the most important criteria when choosing a sleeping bag for backpacking. But the best sleeping bags for car camping are not necessarily the lightest or smallest.
If you are traveling by car, size, and weight don't matter much, and you will probably get additional comfort.
People who move a lot during sleep may prefer a spacious rectangular sleeping bag over a traditional mummy bag. While campers in winter need a perfectly insulated sleeping bag that can withstand sub-zero temperatures.
Whether you're preparing for your next epic Bushcraft Winter Camp or packing the trunk for a weekend in the wilderness - be sure to check out my recommendations for the best single and double sleeping bags.

The Galactic 30 is made of a 50D 300T polyester taffeta shell, making it durable and tear-resistant.
I like that the construction prevents the filling from accumulating at the bottom of the sleeping bag. Additionally, I appreciate the two-way anti-snag zipper, which allows me to fully open the sleeping bag and use it as a blanket.
Alternatively, you can also partially unzip the zipper in the middle to allow air to circulate around your feet. On colder nights, you can use the top drawstring to trap hot air and keep yourself warm.
When it comes to value for money, Kelty is known for producing high-quality camping gear at affordable prices. The Galactic 30, with its included stuff sack, is no exception.
I particularly like the rectangular design, as it allows me to stretch my feet in all directions.

View ProductThe Marmot Nanowave 45 synthetic sleeping bag uses a synthetic insulation called "Spirafil High Loft Insulation". It keeps you warm and dry while camping between spring and autumn (temperature range from 13 °C to -2 °C).
The mummy design with a hood, internal draw cords, and zipper keeps the warmth in and the draft out on cool nights.
It's clear that its narrower shape doesn't offer as much room to move as a rectangular sleeping bag. The two-way zipper is great for camping in the summer.
The Marmot Nanowave 45F is primarily designed for hiking, cycling, and kayaking trips due to its lightweight design and compressibility.
Its high comfort and compact pack size make it, in my opinion, a budget-friendly sleeping bag for car camping and road trips. It's well-suited for people on long journeys or those with limited space in the car.

The thermal collar is extremely useful for freezing temperatures. It can be tightened with a drawstring, similar to the opening for the face.

Things to consider when choosing the best sleeping bags
Types of Sleeping Bags for Camping
As you can see from my list, I divide it into three categories: single sleeping bags for regular seasons, single sleeping bags for cold seasons, and double sleeping bags. There are obviously differences, and we will now take a closer look at them.
Single sleeping bags for regular seasons
Single sleeping bags are generally more versatile because you don't have one large sleeping bag like with a double sleeping bag. And for the times when you want to get cozy with your camping partner, many single sleeping bags can be connected to form a double sleeping bag.
In addition, sleeping bags for the regular seasons are usually cheaper, lighter, and have a small pack size. On the motorcycle, while hiking or trekking, you will make fantastic progress with individual sleeping bags for regular seasons.
Single sleeping bags for cold seasons
Winter sleeping bags are designed for icy temperatures. If you want to go out in autumn, winter, and spring, grab one of the winter sleeping bags from my list.
One thing should be clear to you: winter sleeping bags are heavy, and the pack size is usually so large that you don't transport the sleeping bag on a bicycle. It is better to transport these sleeping bags by car or camper.
Double sleeping bags
The choice of a double sleeping bag over two single sleeping bags may initially deter many people. But cuddling with your partner at night can add more comfort and luxury to your camping trip. Additionally, sharing body heat can mean that everyone stays warmer.
Double sleeping bags are also preferred by people who want to camp comfortably with their dog. And they are ideal for co-sleeping families. In general, double sleeping bags tend to be slightly lighter and less bulky than two single sleeping bags.
My recommendation for a double sleeping bag is the Big Agnes Dream Island 15.
Types of Sleeping Bags for Camping
Usually, there are two types of filling material in sleeping bags.
I will now briefly show you the differences between down and synthetic sleeping bags:
Advantages of down sleeping bags
- Good heat-to-weight ratio
- Sustainable material (if sourced responsibly)
- Can be packed small
- Long-lasting
Disadvantages of down sleeping bags
- Not as warm when wet
- Expensive
Advantages of synthetic sleeping bags
- Insulate even when wet
- Dry quickly
- Significantly cheaper than down
Disadvantages of synthetic sleeping bags
- Not as compressible as down
- Heavy
Since weight and pack size are not really a problem when camping with a car, the lower price of synthetic sleeping bags makes them a much more attractive and practical option compared to down bags.
If, however, you are looking for a single sleeping bag for many camping adventures, a compressible down sleeping bag may be the better option.
If sustainability is a concern for you, you should take a look at synthetic sleeping bags made from recycled materials. More and more companies are also heading in this direction.

Temperature rating
Almost all sleeping bags can be evaluated based on a standardized temperature class. This is practical because otherwise comparing would be difficult.
Basically, sleeping bags can be divided into four temperature ratings, although manufacturers usually only provide two or three:
- Comfort range - the temperature at which an adult woman can sleep comfortably.
- Transition range (Limit) - the temperature at which an adult man can sleep comfortably.
- Risk range (Extreme) - the lowest temperature at which the sleeping bag can keep an adult woman alive. It is a temperature that also poses a significant risk of hypothermia and frostbite.
Both specifications are standardized according to the EN 13537. The EN13537 standard requires a thermal test for sleeping bags, which provides four temperature results: upper limit, comfort limit, lower limit, and extreme limit.
This means that if you stay within the specified temperature range, you will most likely sleep comfortably in a sleeping bag with a comfort temperature rating.
A sleeping bag that you use near the extreme limit of temperatures will help you from freezing – but you won't sleep comfortably in it.
So be sure to consider the temperature rating when choosing a sleeping bag. You need to carefully think about the temperatures you are likely to camp in before making a purchase.
If you want to be certain, then add a few degrees to the comfort temperature and search within that range.
If you can't find the size information, then refer to the filling. Most manufacturers indicate how many grams per square meter are used for the filling. For example, a filling of 700g per m² is suitable for winter. A filling of 300g per m² is suitable for summer.
Types of sleeping bags by temperature
To further narrow down your search for the perfect sleeping bag, most types of sleeping bags are categorized into one of these three types.
| Sleeping bag type | Lower temperature limit (ºC) | Upper temperature limit (ºC) |
| Summer | 1.6 ºC | Above 1.6 ºC |
| 3-season | -12 ºC | 1.6 ºC |
| Winter | -20 ºC | -12 ºC |
Sleeping bag shapes
Generally, sleeping bags can be divided into two forms: mummy sleeping bags and rectangular sleeping bags. Let's now take a look at both forms with their characteristics.
Mummy sleeping bags
In general, mummy sleeping bags are better suited for low temperatures than rectangular sleeping bags. They usually have a hood that keeps your head warm.
Mummy sleeping bags are a fantastic option if you're looking for strong insulation and backpacking. They can usually be packed small and keep you warmer in unpredictable temperatures.
Rectangular sleeping bags
These are ideal for camping trips in the summer when high and efficient insulation is not necessary. Most rectangular sleeping bags can also be completely opened and formed into a blanket. This is very useful in the summer.
And many of them can be connected to other compatible sleeping bags to form a double sleeping bag. Rectangular sleeping bags also offer much more space for sleepers who move a lot or want to bend their legs.
My ideal scenario is that eventually there will only be one sleeping bag that I can use in both summer and winter. And it should also be big and comfortable enough for me to move around in. Unfortunately, this type of technology has not been developed yet.
However, I hope that you are now smarter than before and that you can narrow down your search much better than before my guide.
