Warmlite DOWN Air Mattress (DAM)

Re: Warmlite DOWN Air Mattress (DAM)
I looked thru your images, and seein as how I'm plannin a thru-hike usin a hammock in the future, I have a couple of questions:

Do the DAMs help keep you insulated underneath, during cold weather? I've slept on air mattresses on the floor in the winter and they didn't stop me from feelin that chill in the middle of the night. What would you recommend I place between the DAM and the sleeping bag?

I noticed one of your designs for the wicking systems appeared to be various sizes of whiffle balls. I can see how they would help with sweat evaporation, but how do they affect with the loading of the pack on hips and shoulders? And do those same balls turn into pressure points after a few miles with a load in the pack?

Thanks for any help you can be.
