Oh, I forgot about that guy who made a Cuben fiber hammock. Anybody try one? With a bag pulled around a Cuben hammock, the Cuben would create a vapor barrier to protect the bottom of the bag and a space blanket on top of the sleeper would make a vapor barrier on top. Hmm. That would shave the Nano 7 from 7 ounces down to what, about 2 or 3 ounces if you made a Cuben fiber hammock of the same dimensions as the Nano 7. Right? Hmm.
