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 -24°C. 0.7 is equivalent to a temperature rating of +11°C. The R-Value is not a standard.

Great trekking mattress for Duke of Edinburgh silver. Lightweight and compact enough to carry on the backpack but big enough to provide insulation and comfort.

Lightweight and good value for money. Like the piece of elastic that comes with it to keep it rolled up. A good touch. Bought the thinner mat as lighter but still reasonably comfortable. Perfect for my son's DofE.

We bought these for my husband and son as they were going on a camping trip. They both found them very uncomfortable to lay on. We did wish we had bought an inflatable mattress which is what we will be doing for future camping trips.
