Choosing your sleeping bag is not a matter to be taken lightly. Whether you are going on a trekking over several days, for a weekend hike with bivouac, a night in a refuge, or even for a tented vacation in a campsite, you need a sleeping bag adapted to your needs to have a good night's sleep and ensure you sleep well. As you can see, the choice of sleeping bag is essential for your comfort. We guide you to make the right choice and we reveal you our top 10 sleeping bags.

The weight of the sleeping bag

First of all, it is important to look at the weight of the sleeping bag. Indeed, if you go trekking and you have to carry your sleeping bag all day long, it must be as light and compressible as possible. If, on the other hand, you go on a road trip or camping, you don't wear the sleeping bag, so the weight is not a determining factor for you.
However, it should be noted that if you need a sleeping bag to go on a trek with low comfort temperatures, it will necessarily be heavier.

The comfort temperature of the sleeping bag

All sleeping bags have 3 temperatures: comfort, limit and extreme.
- The comfort temperature: it indicates the temperature where the person is comfortable, that he does not feel cold in his sleeping bag.
- The temperature limit of comfort: it indicates the temperature where the person must curl up on himself not to feel the cold.
- Extreme temperature: this indicates the temperature where the person feels the cold in their sleeping bag and risks hypothermia.
This is the temperature of comfort that you should look at when buying a sleeping bag. It is the temperature that is closest to your comfort, as its name indicates, and therefore the guarantee of spending good nights outdoors. Be careful, if you are rather cold, we advise you a sleeping bag with a comfort temperature a little lower than the temperatures you think you will face.
To choose your sleeping bag, especially if you are going trekking, it is important to identify the geographical area of your hike, the altitudes where you will be sleeping, the season and the weather conditions in order to establish the comfort temperature you need for your sleeping bag.

Sleeping bag padding

The filling of your sleeping bag can also be a factor in determining your choice. For similar temperatures, a synthetic filling is often heavier and less compressible than down, but it is more resistant to moisture. We therefore recommend the synthetic sleeping bag for sleeping under the stars, for bivouacking in humid areas, or if you know that the region is subject to bad weather. The down sleeping bag is often lighter, compressible, insulating and breathable. However, if it gets wet it loses its insulating power, although some down sleeping bags are treated to resist moisture. It is therefore ideal for those who need a light and warm sleeping bag.

Inflation capacity

The loft of a sleeping bag is something to look at for down sleeping bags. It is said that it is good from 650 cuin (cubic inches), it is the capacity of the down and the feathers to trap the air and thus to take volume, literally to inflate to give you heat.

The shape of the sleeping bag

There are 2 types of sleeping bag shapes:
- The sarcophagus sleeping bag allows you to optimize thermal protection by hugging the shape of your body, it is often lighter and takes up less space. It is this shape that is highly recommended if you go trekking.
- The rectangular sleeping bag or blanket sleeping bag is more comfortable because it gives you more space for your feet but it offers less thermal protection because there is more air. They are therefore recommended for summer/spring camping.

The compressed volume

The compressed volume is also an essential element to look at when choosing your sleeping bag, especially if you need to optimize your space in a backpack. If you can't fit the compressed sleeping bag into your trekking backpack, or outside of it, your sleeping bag won't be very useful.
