Thermal insulation and warmth

Sleep on the aluminised side, facing the sleeping bag with the foam side on the ground to minimise losses of body heat. R-Value 1.2 (measured by EMPA, an independent laboratory). The R-Value is a measure of the thermal performance and insulation. The higher the R-Value, the more your mattress will insulate you from the ground. An R-Value of 5.9 is equivalent to a minimum temperature rating of about -24C. 0.7 is equivalent to a temperature rating of +11C. The R-Value is not a standard.

Product test

The bedding comfort or "postural comfort" of the mattresses is defined by our research and development centre. All our mattresses are subjected to mechanical tests on their performance and durability to guarantee the best possible quality of sleep and recovery. We also conduct many tests in the field in real-life conditions.
