Frier Liesel had planned the mat as additional insulation under the air mattress. At the first festival of the season then prevailed at night but only about 4 ° C, since the plan has not worked out. Under the mattress, they did not bring enough, at the end I have the mat, because, taken soft and flexible enough with in the sleeping bag. This has sufficiently warmed and was sufficiently comfortable, although the sleeping pad is not actually intended for.
As an emergency insulation mat has served me well and I'm glad that I had it. Alone saves one but certainly not before winter temperatures.
