While the UL scene rejoiced when the original NeoAir came on the market, I never have been a big fan of it. It was just too cold for me, even on a warm summer night with a CCF pad underneath it. I quickly got rid of it, and have been using CCF pads and self-inflatable mats pretty much exclusively since then. But then Therm-A-Rest presented us the NeoAir XTherm, with a R-Value of 5,7, and they got my attention for that. Now that I have been using this mat since over a year, it is time to take a good, close look at it.
