Arpenaz M100 Trekking Foam Mattress 180x50x0.7 cm - Grey

Dimensions rolled Ø 13 x 50 cm. Volume 6.6 litres. Foam density 30kg/m3.

Indicative R-Value: 1.2 (measured by an independent laboratory). Standardising process ongoing. The R-Value is a measure of the 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 around -24°C. 0.7 is equivalent to a temperature rating of +11°C.Sleep on aluminised side, facing the sleeping bag with foam side on the ground to minimise losses of body heat.

Since the beginning of 2020, a new standard has been validated to assess the level of insulation of your mattress: standard ASTM F3340-18. 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 thermal properties of this Forclaz MH100 foam mattress are pending validation according to this standard. Indicative R-Value: 1,2.

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.
