First off, for the price, this is pretty good pad. I had bought it for my wife but the V-shapes don't fit her size very well as it has ridges or valleys in the wrong places for her. For me the ridges and valleys match my shoulders, hips, knees, etc and I find it comfortable. The biggest grip I have is the R-value is way off. My old thermarest has a R-value of 4.0 and it is significantly warmer the Klymit V's 6.5 R-value. All in all decent pad, good price, fairly comfortable but Klymit needs to get on the international standard of rating the R-value.
