Use temperature
We display the comfort temperatures on all our sleeping bags, tested by an independent laboratory (AITEX) in compliance with European standard EN 23537-1 from 21/01/2017. The comfort temperature is the lower limit at which the user, in a relaxed pose, is in overall thermal equilibrium and feels neither too cold nor too hot (for a standard woman in normal conditions of use).
Choose your sleeping bag accordingly.
What is the comfortable temperature limit?
The comfort limit temperature is the minimum temperature at which the user, huddled up in the sleeping bag, is generally in thermal equilibrium and feels neither too cold nor too hot (for a standard man under normal conditions of use).
What you need to know about temperatures
A sleeping bag does not produce heat, it 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 (bulk, fatigue, etc.), equipment (mattress with insulation, etc.), clothing (naked, underwear, etc.) and weather conditions (damp, wind, etc.).
Tips before getting into your bag
Dress simply (1 layer of clothing is enough). Keep your head, hands and feet warm: use hats, gloves, socks, bed warmers, rubbing, etc. A flask filled with hot water can be used as a hot water bottle (if it can't open by accident!). 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.
To avoid washing your sleeping bag too often, we recommend you use a sleeping bag liner.
Composition
Inner and outer fabric: 100 % polyester | Wadding: 100% polyester wadding (200 g/sqm).
Ecodesign
We have chosen a two-tone "dope-dyed" liner fabric and "dope-dyed" thread to reduce the environmental impact of this product. The yarn is dope dyed during the manufacturing process, avoiding the use of dye baths. One of the threads is dope dyed, the other not. Below, the results compared to a classic liner fabric:
-65.8% fine particle emissions (PM2.5)
- 65.6% Eutrophication of fresh water
- 76.7% eutrophication of sea water
