Quite a few reports on BPL recently of the new, lighter NeoAir developing leaks at the seams. This happened when the original NeoAir first came out, too. Evidently a new product issue.

I've been told that Thermarest is really good about such issues--they'll fix it or give you a new pad. Even if you obviously punctured it, they'll fix it for a very low price.

I certainly bounced around on mine a lot before I returned it because it was so uncomfortable! No leaks, just that the horizontal baffles didn't work at all for me, and I couldn't find a sweet spot between too little and too much inflation. It was one of the early ones, too.
