I’m curious to know other people’s opinions on NeoAirs. I bought an XTherm last year for winter camping and I was really surprised to find that I just didn’t like it. It seems so weird though, because NeoAirs generally get really good reviews. I found that, no matter how much air I let out of the mat, it still felt as hard as a rock after a few hours. My arm would constantly fall asleep and I had to keep rolling from side to side. I also found that it felt much narrower than other mats. The tapered shape is rather aggressive, and the sides collapse if you get too close to the edge. It made my 20” mat feel like it was 16” wide.
Also, the mat felt warm when I went to sleep, but if I started to get cold, I felt like the mat got colder too. Please correct me if I’m wrong, but my understanding is that our bodies produce radiant heat, but the amount of radiant heat is proportional to how warm we feel. So, if we feel warm, a radiant barrier will keep us warm, but if we’re feeling cold, a radiant won’t be as effective. Because XTherms rely heavily on radiant barriers, is it possible that they aren’t as effective if you start to feel chilled overnight?
Am I the only one who doesn’t like NeoAir’s? I recently replaced my XTherm with a Sea to Summit Comfort Plus Insulated, and it feels way more comfortable so far. I’ve yet to try it outside though.
