Whenver I buy something strange like a one piece long underwear suit I am always skeptical. This suit has made me a believer in total comfort, warmth and function. I am 100% amazed at the design of this. They really thought of everything and made it function perfect. Mine does not fit me 100% how I would like but I have a strange body type so I am sue to that. It is really awesome and I am going to get another one!
