Thermal properties and warmth

Sleep on the aluminized side, facing the sleeping bag with the foam side on the ground to minimize the loss of body heat. R-Value 2.5 (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 the mattress insulates you from the cold ground. An R-Value of 5.9 means a minimum temperature of use of approximately -11°F. 0.7 is equivalent to a temperature rating of +52°F.

Thermal properties and warmth (2)

The R-Value is not a standard, each manufacturer can use their own criteria. A standardization process is currently underway.

Comfortable postural support

For a foam mattress, this mattress offers a greater level of comfort thanks to its design and the depth given to the foam by the mold. This specific design allows for 0.8" mattress thickness, giving home comfort and real postural support.
