Product Customer Reviews
I recommend
Very good, light and practical
Practical, folds up very easily. Very light to carry. Good insulation.
very good exercise mat, foldable not rolled up, which makes it easier to transport and you can always lie on the side that is not on the ground :)
Bought this years ago and still going strong. Light, comfortable and warm.
Versatile, serves to sit without unfolding it. Folded in two it increases the R value and comfort on difficult terrain.
Comfortable and practical, foldable in an instant. Although I have not yet tested it in extreme situations, but certainly a good product
Very good groundsheet. Its advantage is also its disadvantage, it is too big to fit in the bag but at least you can turn over on it during the night. Tested with negative temperatures in a tent (-3°C, -6°C).
It is a light and useful mat. Its price could be a little more reasonable. I think I will enjoy using it.
Nice, comfortable sleeping mat. Easy to fold and very light. Quite good insulation. I recommend
great product that accompanies me on every night in nature, I recommend it
Quite comfortable
Good insulating floor mat. As the insulating R is added, I paired it with an air mattress for better insulation. Lightweight, comfortable at a fair price. Only the bulkiness and maybe sometimes problematic, other than that good product.
Comfortable, lightweight and insulating
Great, very soft, makes nights comfortable!

What is the r-value?
The R-Value is a measure of the thermal insulation. It measures the ability of a mattress to retain or prevent heat from escaping from a warm body (human body) to a cold floor.The higher the R-Value, the better the insulation of the mattress.Please note that the R-Values can be added; this means that you can use two mattresses and add their R-Values.All our mattresses are tested to standard ASTM F3340-18.
What r-value for what use?
R-value from 0 to 1.9: Hot season (summer) onlyR-value from 2 to 3: 2 or 3-season (spring-summer-autumn)R-value from 3 to 4: 4-seasonR-value of 4.5 and higher: Use in all 4 seasons and in extreme conditions (glacier, far north and high altitudes)
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 mould. This specific design allows for 2 cm mattress thickness, giving home comfort and real postural support.
