I ordered two of these mats and used this about 5-7 times to camp. (Nothing extreme, just sleep only with a minimum of 5 ° C in Germany in a tent) Even if the mat is self-inflating, can be done by the mouth, if you want to sleep comfortably (but that is normal for Self-inflating mats). The mat is indeed thick and large and so comfortable, but also difficult. That does not bother if you drive by car to the campsite, I want to wear it all day on the mat but not backpack. A mat loses now on air shutter, which is indeed little (You can hear it only if you plan rests her head on the right side), but that is not the mat meh useful
