We display the comfort temperatures on all of our sleeping bags, tested by an independent laboratory (AITEX) in compliance with International Standard ISO 23537-1: 2022. The comfort temperature is the minimum temperature that an average person (woman, 25 years old, 60 kg, 1.60 m) is at ease, without feeling cold, in a relaxed position.Choose your sleeping bag according to this criterion.

The temperature limit is the minimum temperature at which an average person (man, 25 years old, 70 kg, 1.73 m) can sleep curled up without feeling significantly cold.And for information, the extreme temperature is the minimum temperature at which a person can survive (risk of hypothermia) for 6 hours.It is a measure of safety, and not of comfort.
