Oh, one last bit of advice.........when you roll your mat be careful to allow time for the trapped air to escape the valve. There are murmuring of air leaks at the ends. My suspicion, just a hunch mind you, is that inordinate amounts of pressure are being exerted when rolling the mat.

I think your probably right and you should use caution with any air filled type sleeping mat.

I don't know how other's go about it, but I use this method, and it seems to make the whole deflation/packing process work better.

I'm in the habit of packing all my sleep gear BEFORE I exit tent to make breakfast on travel days. Once I decide to roll out of bed, I open the air valve and allow my body weight to deflate the mattress as much as possible. Then I close valve and put bag/pillow in stuff sack. Then I start rolling the partially deflated air mattress leaving the valve closed until resistance is met. Then I open valve and finish rolling out air.

This makes for a quick deflate and keeps me from getting over zealous and possibly/probably putting to much air pressure on air valve seam end. I see the difference, but let others judge for themselves ;)
