Thermal protection and heat
Sleep on aluminised side, facing the sleeping bag with foam side on the ground to minimise losses of body heat.
Indicative R-Value: 1.2 (measured by EMPA, an independent laboratory).
The R-Value is a measure of thermal performance and insulation. The higher the R-Value, the more the mattress insulates you from the cold ground.
An R-Value of 5.9 means a minimum temperature of use of approximately -24°C. 0.7 is equivalent to a temperature rating of +11°C.
Thermal properties and warmth (2)
Since the beginning of 2020, a new standard has been validated to assess the level of insulation of your mattress: standard: ASTM F3340-18.
The Forclaz mousse M100 mattress is undergoing normative testing.This standard measures the capacity of the mattress to retain or return body heat in order to avoid its loss and therefore provide you with thermal comfort.
The sleep comfort, also called "postural comfort", of our mattresses is defined by our R&D centre. All our mattresses are subjected to mechanical tests to assess their performance and durability and ensure you enjoy a good night's sleep and an excellent recovery. We also carry out numerous field tests in real-life conditions.
