extremely happy with my synmat 7 deluxe. played around with thermarests for a bit, but the comfort factor, and the packability won them all over even though a higher price tag and heavier weight. the neoair looked like a good contender for packability - didnt know many reviews and at $130 didn't want to be the one experimenting... however now the reports are coming out that it is durable and worthwhile, just may not be as versatile as your synmat 7 in the same temperatures.
