After the mat opening the strong and pungent smell noticed. This vanished after two days of airing. Would hold that the aluminum coating to the stony ground of the Canary Islands not unscathed, was to be expected and does not lead to a lower assessment for me.
Negative noticed that the foam is so soft and easily deformed. Supports one example, the elbow or on one is on the side (and thus has a smaller contact area than on the back or stomach), separates a only a hard millimeter aluminum and together pressed foam from the floor.
Very positive was the low weight and the insulating effect. Here, the mat has met my expectations and left no cold from the ground.
Overall I would say, the product is only limited suitable sole base for the night. However, as an insulating layer between the ground and an additional comfortable mat it meets the requirements. When they are placed on a firm ground sheet and not directly on rough and smooth, should the above-mentioned damage to the aluminum does not easily occur.
