I don't think its that simple Mike, I've done plenty of cold weather hangs with lots of CCF insulation between the layers( Stacked and side by side) and know that its as warm as my winter down UQ.
When I use my 2/rds UQ, the ends of the hammock are completely uninsulated which should cause even more condensation than with CCF, but it doesn't-I stay completely dry in this too.
The only difference between the 2 as far as I can see is a greater amount of dead space surrounding the foam pads due to increased folding, causing convective cooling between the layers.
Just to clarify, this is with my DD travel non-breathable, so the breathability of the fabric isn't a factor in this comparison
I thought bmartin1uk was referring to not having any form of insulation V UQ?
