New favorite pad!
I have the synmat 7 pump and have been using it for a little over a year; no complaints yet! It is like sleeping on a cloud as others have said and a huge improvement over my thermrest prolite plus, that extra inch is a big surprise!
The pump is nice and takes in the surrounding air and not your hot breath allowing it to hold in air better. The pump takes a bit getting use to, but once you find the right rhythm it inflates fast (about 1 min). The material is durable too. I use this year round and don't get too hot.
