Product Customer Reviews

Used to protect the walls of my garage from possible friction from the vehicle.... I already had several, it works very well 😀
The truth is that with sleeping it doesn't get cold. But for my taste it is very small in width, you can literally only sleep on your back with your arms crossed because if you move in any way you will fall off the foam and for me that is very uncomfortable. IT WOULD BE PERFECT IF IT WAS WIDER
not very thick, allows you not to be on the ground
Very good for its price
Excellent price/quality ratio! Very comfortable...
Very fast
utility outside of sport, the most resistant from Decathlon, bravo for the concept
Purchased to protect against humidity and cold rising from the ground. Effective, the mattress is no longer damp in the morning. The ideal would be 2 mattresses side by side because it is not wide enough. To see the solidity over time
I recommend .
A sleeping mat perfect for a tent
It is a very light and comfortable product, practical for when you need something to insulate under a mattress.
Good product
Very thin and light. I use it for insulation and additional protection under an inflatable mattress.
Improves outdoor insulation
A 100% recommended product

Thermal properties and warmth
Sleep on aluminized side, facing the sleeping bag with foam side on the ground to minimize losses of body heat.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 is equivalent to a minimum temperature rating of approximately -11°F. 0.7 is equivalent to a temperature rating of +52°F.R-Value is not a standard (in progress).
