I think that's the idea with the HH Super Shelter. The Super Shelter uses a SilNylon layer under the hammock for a windbreak and uses a 1/4" open cell contoured pad for insulation. The open cell pad grips and holds other pads in place.
I use a 3/4 length ThermaRest UL pad between the open cell pad and the hammock. It has kept me warm to around 30 degrees. That's as cold as I have been able to test it. Two weeks ago on the AT it go into the upper 30's and I was warm. From 40 degrees and up I actually have to shed clothing. I took a small closed cell pad (~10"X16") for sitting on the ground. I used it inside under my knees or where ever a cool spot developed as I shifted around.
I dislike wrestling with a pad inside the hammock. It never seems to want to stay where you put it.
