Keith W.wrote a review of Big Agnes Insulated Air Core Sleeping Pad - Rectangular on June 4, 2009
I've been very happy with this pad, used it in warm (65 at night) and cold (25 at night) and always been comfortable. A big adavantage is that I can deflate it a little after lying down on it and it can smooth out bumps and even some slant to the ground you're lying on. I'm fairly sensitive to sleeping on a slant and this pad has helped a lot. I'd absolutely recommend it.
