I successfully used Gossamer Gear CCF pads in my HH Backpacker UL in the 22F range for several years by placing/wrapping the pads in a flannel sheet which absorbed the condensation. The flannel was damp, but not wet in the morning, and my sleeping bag was perfectly dry. This was 10 or 12 years prior to me trying Vapor Barrier clothing.
There were Space Blanket experiments at the time and moisture was always an issue because I didn't know to insulate under the space blankets.
I never laid directly on the CCF pads, I always laid on a sleeping bag. Early usage (2006 era) I had not tried the flannel yet and my sleeping bag was quiet damp in cold temps (I think mid to low 30's was considered very cold hammock weather then). After a year or so of sleeping in damp bedding I tried wrapping the CCF pad in an old flannel sheet and voila - my sleeping bag was dry and flannel absorbed the moisture. I stated my success on HF and got the 'cotton kills' replies - it sure worked for me. I don't know the science, but here are my thoughts:
I think it is not condensation from the outside air, but this is
condensation of the moisture your body puts off and it is concentrated in the trapped area right under you. My flannel sheet wrap was always dampest right under - maybe the exposed flannel just allowed evaporation, I don't know.
I've never used a double layer hammock, but I would say this alone would not negate the moisture development on a CCF pad if the pad is held tight against the sleeper.
The modern ribbed blow-up pads will allow some air movement, so CCF would have to be used for testing for condensation in cold weather.
Are these double layer pad insulated hammocks designed for and being used below 32F? or do folks use them above about 40F?
I predict BillyBob is chomping at the bit to pull out his CCF pads and give it a test run this winter - or is using that PeaPod just too much comfort to turn down
