I bought this pad and used it in my WBBB, and have had it for a couple years now. Since I have switched over to a WBRR, I am going back to using an UQ insulating system, so I really dont need this pad anymore. I am selling both the pad and the Pumphouse Pad Inflating dry sack for it. The sack works great, and keeps the inside from getting any moisture from your breath-great in colder climes. I am selling these together. The cost includes shipping to the lower 48 (sorry, no overseas, canada, etc folks). The pad has only been used a handful of times, never on the ground, only in between hammock layers. The pad is the regular size, the R value is 5.
