Neo, I tried your idea with the pad and windshield reflector. The temps went down to about 24*F. Wow, was it cold. I did get a little chilly, but not nearly as cold had I been using a UQ. For some reason the pads just tend to keep me much warmer.
It kept me warm, yes, however, when I woke up my back was wet and so was the bottom of the hammock. I believe this is from condensation from covering my head while sleeping. I don't recall having this issue while using a pad alone, without the reflector. It seems the pads are breathable or something. I've slept with my head covered many times without any dampness what so ever.
Come to think of it, I even had minor dampness issues while using a down UQ and a down OQ.
Any suggestions on how to prevent this from happening and turning my bed into a death trap?
My first thought was to not cover my head, but I tend to get a lot cooler that way. Yes, I was wearing a hat. Maybe a baklava, and ski mask or something.
