Like other reviewers, I've tried many pads: was almost going to keep my Therma-Rest Neo-Air X-therm, great insulation, but too noisy and not as comfortable as the NEMO. This is a great, warm pad, and is the most comfortable compared to the noisy Therma-Rest and Big Agnes, and ExPed. I truly believe for the value, and incredible warmth, this is the best pad out there. Although NEMO does not provide R-ratings, this kept me warm down into the low 30's in the Santa Monica mountains using my Enlightened Equipment Revelation quilt. I was colder in early morning, but put on a thermal shirt that did the trick. Easy to inflate, and weighs less then their new pad with release valve and foot pump.
