We display on all our sleeping bags the temperature ratings tested in an independent lab (AITEX) based on International Standard ISO 23537-1: 2022.The comfort temperature is the minimum temperature at which an average person (woman, 25 years old, 60 kg, 1.60 m) is comfortable, without feeling cold, in a relaxed position.Choose your sleeping bag based on this feature.

The comfort limit temperature is the minimum temperature at which an average person (male, 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. This is a safety measure, not a comfort measure.

The protocol for measuring the thermal properties of a sleeping bag uses a mat with a thermal resistance corresponding to an R-value of 4.8.If you use a less insulating mat, the thermal performance of your sleeping bag will be reduced.We therefore advise you to use an insulating mat for better thermal comfort.
