Les performances thermiques du sac de couchage Hamelin selon la norme ISO 23537-1:2022:

The standard defines two temperatures, “Comfort” and “Lower Limit” to evaluate the thermal performance of a sleeping bag.
This standard makes it possible to compare the different models on the market and to help the practitioner in his choice.

- Comfort temperature:

This temperature corresponds to the temperature of use for which one expects to sleep relaxed.
If you are chilly or a woman, use this size to choose the model.

- Lower Limit temperature:

This is the temperature at which a standard human can sleep for eight hours in a curled up position without waking up.
If you consider yourself a high body temperature sleeper, use this value to gauge the coldest temperature the bag can be subjected to.
