Technical information

Use temperature

We display on all our sleeping bags the comfort temperatures tested by an independent laboratory (AITEX) according to European standard ISO 23537-1 of 21/01/2017. The comfort temperature rating is the lower limit at which the user in relaxed posture is generally in thermal equilibrium and feels neither too cold nor too hot (for a standard woman in normal conditions of use).
Choose your sleeping bag according to this criterion.

What is the comfort limit temperature?

The comfort limit temperature is the temperature limit at which a person curled up in the sleeping bag is in general thermal equilibrium, neither too cold nor too hot (determined for a man in normal conditions of use).

What you need to know about temperatures

A sleeping bag does not produce heat, but retains the heat produced by the body. If you are tired and cold and you slip inside a cold, damp sleeping bag, it is very likely that you will feel cold no matter how good your sleeping bag is! These temperatures therefore depend on the person's resistance to cold (body type, fatigue, etc.), equipment (mattress with insulation, etc.), clothing (naked, underwear, etc.) and weather conditions (humidity, wind, etc.).

Tips before getting into your bag

Dress simply (one layer of clothing is enough). Warm-up your extremities: hats, gloves, socks, hand-warmers, padding, etc. A flask of hot water can be used as a hot waterbottle (as long as there's no risk of accidental opening!). Contract your muscles (70% of the energy consumed is converted into heat) but without making any movement generating a cold airstream.
To wash your sleeping bag less often, we recommend you use a sleeping bag liner.


Outer fabric and lining: 100% polyester | Wadding: 100% polyester 100 g/m² wadding.

Washing your sleeping bag

We recommend you use a washing machine with a minimum 7 kg capacity and close the zips on your sleeping bag.
