Worth every $. I would never get a different sleeping pad. This insulates like crazy, is super comfortable, easy to inflate, has a huge vent to deflate, well placed baffles. The material is rugged yet not too heavy. I also stopped slipping off the pad during the night due to the material used on the surface of the pad and the well placed baffles. I am 5'10 and got the 7 Pump M which works great for my size.
