Considering changing up my pad configuration and wondering about doubling up pads.
Specifically, I like to take a cut down a thermarest z pad for sitting/glassing during the day. I am wondering if I were to use the z in combination with an insulated inflatable would the R value effectively increase to the addition of the two R values to one combined new value or is there some R value efficiency lost.
Also, if stacking them what is the experience with putting the Z pad on top of or underneath the inflatable, again assuming that the z is cut down to torso length only.
Thanks for the replies.
