I was a little skeptical about a self inflating air pad but man did it work. You will still have to add a few self breaths of air to get it to its full thickness but it certainly made it easier. I do not think I'd backpack again without it. I highly recommend rolling it up as tight as possible allowing for all the air inside to be dispelled. When you open the nozzle let the airpad itself unravel then add air to comfort level.
