How is the comfort temperature rating of the ULTIM COMFORT 20 °C sleeping bag determined?
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 accordingly.

What is the ULTIM COMFORT 20 °C sleeping bag made up of?
Inner fabric: 100% organic cotton | Outer fabric: 100% polyester pongee | Wadding: 100% polyester 100 g/m² wadding.
Is the comfort temperature rating the same for everyone?
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.).
What to wear when sleeping in the ULTIM COMFORT 20 °C sleeping bag
To use the ULTIM COMFORT 20°C sleeping bag, you’ll be warm enough if you wear a single layer of clothing. Warm up your extremities with hats, gloves, socks, hand and feet warmers, etc. A flask of hot water can be used as a hot-water bottle (be careful that it doesn’t open accidentally!). Contract your muscles (70% of the energy consumed is converted into heat) but don't make any movements that cause cold draughts.
To avoid washing your sleeping bag all the time, use a sleeping bag liner.
