Like Sleeping in my bed!
This pad is a must for 4 season camping. I bought the Synmat 9 and really enjoyed the extra length and width since I am 6'4" 190 lbs, and I couldn't fit comfortably on the synmat 7 I bought my wife. The pad is SUPER WARM! First night on our Kilimanjaro trip I sweated really bad since I was fully zipped in my 15 degree bag and it was only 30F outside. After that I slept straight on the pad with my bag just draped over me wearhing shorts and a long sleeve T and was warm even at high camp (15,000 ft). It is a little heavy to carry on a really long trip in the summer if it is warm out, but it is definately my new car camping pad.
It took me about 3 minutes of straight pumping to get the 9 pumped up, and it takes about 1 minute to roll it up. Didn't lose inflation at night one time.
