Taking the boy this weekend for a quick overnight in the piney woods of MS. Low is expected down to 35+. I have a lot of Reflectix left over from my cosey making and wondered the following:

Take a length of reflectix lay in the bottom of a HH Expl and HH Expd, place sleeping bag on top and go from there.

I have read all the threads on condensation, etc. Just wondering if this is a really bad idea for one night or a good idea for one night (and maybe beyond). I will be getting a UQ at some point in the future for me and likely for the boy since it looks as though he is going to be gung ho on this, but in the short run, Thunbs up or Thumbs down.
