Choose a sleeping bag

Choose a sleeping bag

The sleeping bag that is right for you depends on what you want it for and which features are important. Lightweight and packable for a summer trek and travel or a lot of heat for winter use? Here is a check list of the things you should consider in order to find a sleeping bag that fits your needs.

Johan Skullman our outdoor expert and product specialist gives his best tips on choosing a sleeping bag.


A good rule of thumb is to be prepared for cold temperatures. Choose a sleeping bag that can handle lower temperatures than the lowest temperature you expect. You can always unzip for ventilation if you get too warm. For summer use in the mountains you will need a sleeping bag that can handle around –3°C. For simpler camping and travel in warm countries, a thinner sleeping that can handle temperatures around +10°C is sufficient. In the spring and autumn you will need one that can handle around –10°C and in the winter around –20°C. These recommendations are simply approximations, however, since perceived temperature is personal.

Total weight

How much weight do you want to carry? If you are kayaking or pulling your sleeping bag on a sledge, weight might play less of a role, but if you are trekking many kilometres, a heavier sleeping bag makes your backpack unnecessarily heavy. Down sleeping bags are often lighter than synthetic sleeping bags.

Packed size

Even if a sleeping bag is light, you should keep looking if it is very bulky. Space is often precious, particularly when trekking with a backpack, and you may need the space for something else – food, for example. A down sleeping bag usually can be compressed to half the size of a corresponding synthetic sleeping bag.

Length and volume

Fjällräven sleeping bags come in two lengths: Regular (170 cm) and Long (195 cm). You should choose one that is big enough for you without it being too tight or too roomy. If a sleeping bag is too tight, the padding gets pressed together, which hurts its ability to insulate. If, on the other hand, a sleeping bag is too large, your body volume will not sufficiently heat up the air inside.

Insulation of a sleeping bag

There are two main types of sleeping bags, down and synthetic. Both materials have their strengths and weaknesses

How do you sleep?

Do you move in your sleeping bag or do you move with your sleeping bag? Almost an equal number of movers and twisters are out there.  We decided to offer one model of our premium down sleeping bags with an optimized fit towards these two sleeping styles. Move in Bag is designed for people who move inside the sleeping bag, while the bag itself stays put on the ground. Reinforced insulation with 60 per cent of the filling at the front side of the bag gives great warmth where it is most needed. Move with Bag is designed for people who take the sleeping bag along in their movements, keeping the hood opening at the front of the body at all times. Equal distribution of down at front and back ensures good insulation no matter what position you sleep in.
