Operating temperature
We display on all our sleeping bags the comfort temperatures tested by an independent laboratory (AITEX) in accordance with European standard ISO 23537-1 dated 21/01/2017. The comfort temperature is the lower limit of comfort at which a person in a relaxed posture is in overall thermal equilibrium and neither cold nor hot (determined for a standard woman and under normal conditions of use).
Choose your sleeping bag according to it.
What is the comfort temperature limit?
The comfort temperature limit is the temperature at which a person curled up in a sleeping bag is in overall thermal equilibrium and neither cold nor hot (determined for a man and under normal conditions of use).
What you need to know about temperatures
A sleeping bag doesn't produce heat; it retains the heat produced by the body. If you're exhausted and cold, and you slip into your icy, damp sleeping bag, you're likely to be cold, no matter how good it is! These temperatures depend on a person's resistance to the cold (build, fatigue, etc.), their equipment (mattress insulating from the ground, etc.), their clothing (nude, underwear, etc.), and climatic conditions (humidity, wind, etc.).
A few tips before you slip into your bag
Dress simply (a single layer of clothing is sufficient). Warm up your extremities: hats, gloves, socks, warmers, frictions, etc. A flask of hot water can be used as a hot-water bottle (if there's no risk of opening it unexpectedly!). Contract your muscles (70% of the energy consumed is transformed into heat), but without making any movement that generates a cold draught.
For less washing of your sleeping bag, we recommend using a sack sheet.
