Use temperature:
On all our sleeping bags, we display the comfort temperature rating tested by an independent laboratory (AITEX) in compliance with European standard NF ISO 23537 - 2017.
The comfort temperature is the lower temperature at which a user in a relaxed position is generally in thermal balance and is neither cold or hot (determined for a standard woman, in normal conditions of use). Choose your sleeping bag according to this rating.
What are the limit temperature of use?
Limit temperature rating: temperature at which the sleeping bag user in a hunched position is in thermal balance ans is neither cold nor hot (determined for a standard man and in normal conditions of use).
However, what you need to know about these temperatures:
A sleeping bag does not produce heat, but retains the body's heat. If you are tired, cold and that you slip into your sleeping bag frozen and damp, you will be cold, no matter what its quality! These temperatures therefore depend on how resistant the person is to the cold (body type, fatigue, etc), their equipment (mattress to insulate from the ground, etc), whether they are dressed or not (naked, underwear, etc) and climatic conditions (damp, wind, etc).
For more comfort when you slip into your sleeping bag:
Dress simply (1 layer of clothing is enough). Warm the ends of your limbs: a hat, gloves, socks, heating pads, friction... A flask of hot water can be used as a hot water bottle (if there is no risk of it opening by accident!) Contract your muscles (70% of energy is transformed into heat), but without making movements that will cause draughts of cold air. Use a sleeping bag liner, ideally silk, to increase warmth of your sleeping bag.
Shape:
"Generous" mummy shape: Wide shoulders and tighter around the feet to optimise thermal insulation (no loss of heat) and compactness, while retaining relatively good freedom of movement.

Ergonomic hood with drawcord.
Two side zips with double cursors and anti-cold wadded flap (heat bridge), side openings.
