When I lay down on the pad, I could just feel the heat re-radiating from my torso, it was great. However, this pad is quite noisy/crinkly, so for example on a recent trip with shared tents, I opted for my more traditional pad. I might have to wear ear plugs myself to sleep on this NeoAir. It's less noisy when a bit less inflated.
