I've kept me in mind, to support the mat previously inflated. In 10 days camping holiday I've packed and unpacked it almost every day. the first after it was Zeltaufbau permit matte purely throw and unfold, it takes a little. My mat all the time the air well kept. Man slips on her not down with inclined bottom. Also goes inflating faster, the more "exercise" has the material. I would buy this mat again.
