I bought your mattress because I hope a 10cm wanted mat & have also taken for the slightly larger pack size into account. (The mat is extremely unfavorable to transport as well as on the packaging no wrist strap is attached.) However, this is not the reason for my dissatisfaction. As I said I wanted to have a 10cm high insulation pad. I get a 6 cm high, even after trying several times and Nachpusten (which has already irritates me at a self-inflating sleeping pad) is here with no distance possible to reach the 10 cm. It sleeps up quite well to 6 cm well, no question. However, if I want to have ordered 10cm also get 10 cm, so I feel just simply duped.
