On all of our sleeping bags, we display the comfort temperatures tested by an independent laboratory (AITEX) according to European standard NF ISO 23537 - 2017.The temperature rating is the lower limit at which the user is generally in thermal equilibrium and feels neither too cold nor too hot in a relaxed pose (for a standard woman and in normal conditions of use). Choose your sleeping bag according to the latter.

Limit temperature:temperature at which the user huddled up in the sleeping bag is generally in thermal equilibrium and feels neither too cold nor too hot (defined for a standard man under normal conditions of use).

A sleeping bag does not generate warmth but retains the warmth produced by the body. If you feel tired and cold and slip into a cold and damp sleeping bag, you are likely to feel cold, however good it is! These temperatures therefore depend on the person's resistance to the cold (bulk, fatigue, etc.), their equipment (mattress that insulates from the cold, etc.), their clothing (naked, underwear, etc.) and the weather conditions (humidity, wind, etc.).

Dress simply (just one layer of clothing is enough). Keep your head, hands and feet warm: hats, gloves, socks, hand or feet warmers, rubdown, etc. A bottle full of hot water can be used as a hot water bottle (as long as it will not open accidentally!) Contract your muscles (70% of the energy consumed is transformed into heat). However you should do this without moving as this can cause draughts of cold air. Use a liner sheet, ideally made of silk, to optimise the warmth inside your sleeping bag.
