How do we determine the operating temperature?
All our sleeping bags display comfort temperatures tested by an independent laboratory (AITEX) and based on the European standard EN 13537 of 11/04/2002.
Comfort temperature is the lower limit at which a person in a relaxed posture is in thermal equilibrium, i.e. neither hot nor cold (determined under normal conditions of use).
Choose your sleeping bag according to these values!
What you need to know about temperatures :
A sleeping bag does not produce heat but retains the heat produced by the body.
These temperatures therefore depend on the person's resistance to the cold (build, fatigue, etc.), their equipment (mattress insulating from the ground, etc.), their clothing (nude, underwear, etc.) and the weather conditions (humidity, wind, etc.).
If you are tired and cold and slip into your cold, damp sleeping bag, you are likely to feel cold, whatever its qualities!
Special for children:
Choose a sleeping bag adapted to your child's size.
In fact, the greater the volume of air to be heated, the more energy the body will expend, and the greater the risk of chilling during the night.
Similarly, a large proportion of a child's heat loss occurs through the head.
In cool weather, don't hesitate to put on a hat.
Washing your sleeping bag
We advise you to use a washing machine with a minimum capacity of 7 kg, and to zipper your sleeping bag securely.
