>>963911>>963911PS they also have an insulated version with R of 4.3 (Klymit Insulated Static V Lite) that looks about 20% larger and costs +30$ and probably weighs just about the same but I still think you're better off with the thermarest at that point. The klymits are shorter but wider than thermarests. I'm 6'2" and I find the klymit just a little short. I also weigh about 150lb and understand when you're over 200lb these might not be the best choice. hope that was all useful.
