Best praise vs top criticism for Therm-a-Rest NeoAir XTherm
Best Praise
+108 pts“I don't find this to be the case, at least around the Sierra where I hike. I use an XTherm year round, sleep pretty warm, and don't really have issues. When I'm hot, my inclination is to remove or open up my bag, not change my mattress.”

+11 pts“This is where I would start. Guessing you use an insulated XT version, if so then I have the same pad and I find it starts fading around -2/3C. It's notably colder than my old gen tensor insulated and the new thermarest Xlite NXT. Try testing it with another layer, ccf, reflective sheet, etc, to see how much it helps. It won't matter how good the quilt/bag is if your losing heat from the ground.”
