Now the negatives: The description says that the mat in seconds even inflates. This is of course nonsense. Anyway, when the two mats that I own. I rolled up the mats and the valve is opened and .... nothing. Even after an hour ... nothing. On the internet I have read the notice that you should they inflate the first time so (which is not easy, since the cover of the valve can not be removed). Said and done. Then again rolled up to the test and then rolled back and open valve. The mats blow now put themselves on, but of course not in seconds and in some cases incomplete.
Another negative point is the enormous weight and the size of the mats. Curled Eng weighs the 10cm mat about 2.5 kilos (as much as a good 2 person trekking tent) and is a fairly thick, 66cm long roll. For trekking the mat is thus rather unsuitable. I mention this only because the mats are the same when displayed on Amazon looking for "sleeping pad". These monsters (nearly) mattresses have few to do with the traditional sleeping pad.
All in all from me a recommendation. I any case they do not want to miss the tents.
