Warm and relatively easy to inflate for a hand-pump mat. Not as easy to inflate as a mat you simply blow up, but it does avoid introducing moisture from your breath into the air chambers. I like the shape at the shoulders; on regular flat (e.g., 20 inch wide thermarest) pads, I find my arms falling off the sides. With the head-to-toe oriented air chambers, my arms stay on the pad and off the cold ground. Can't speak to durability as I've only used it a few nights.
