It got a little cold last night. (-6C/~23F) I woke up to a thick frost all around me on the ground. But there was a small problem; The entire inside (top and sides) of my hammock (especially the bug-netting) was frozen and/or wet.
I woke a couple of times throughout the night because my goatee was frozen to my pillow. (that hurts by the way!) I can only assume that the condensation from my breath was what caused the excessive amount of moisture inside my hammock. I was dry underneath me and quite warm (JrB Quilts FTW!) but I did have to don my goretex balaclava midway.
