That's what I was thinking you were talking about.
Isn't it ccf on the bottom and open cell on top?
Just brainstorming, but I wonder if an inflatable pad might work. It wouldn't need to be inflated in the hammock, but would provide an extra layer that would help some in cool weather. If you need to go to the ground, just blow it up. Much more comfy than ccf, even the z-lite, on the ground.
