Comfort temperature -5°C

For these sleeping bags, the comfort temperature has been tested in an independent laboratory following 2017 European standard ISO 23537-1. This temperature represents the lower limit at which the user is in thermal equilibrium, neither feeling cold yet warm (determined by a healthy woman under normal conditions of use.

Temperature limit -11°C

The limit temperature represents the lower limit of thermal comfort at which the user's body is in thermal equilibrium (the person is neither cold nor too hot). Determined for a healthy man and standard user conditions.

The lower limit at which there is a risk of health damage due to hypothermia. The sleeping bag should not be selected for this, this serves as an informative indicator of danger. The sleeping bag will have to be used above this temperature.
