Well It wasn't in the piney woods but my unheated garage no side door , Garage door has 4" opening on the top and Bottom so plenty of draft low 19 ° F . I used my WB Traveler hung off the steel beam just long enough to get a flat lay. Had my new winter Incubator from Hammockgear and a 20 ° F Montbell 650 Down bag as top quilt and a thin texas sport fleece zipper throw as a liner. Hung everything at 1 pm EDT so to be good and cold when I went to bed at 9:30 PM EDT Clothing worn was a Poly/wppl blend walmart Long Johns top and bottom and thin nylon jogging pants and a walmart fleece top also had a fleece/ Poly Balaclava on and my fleece/Poly face mask and thing knit cap. Well shortly after getting settled in I had to adjust my straps for a diagonal flat lay feet were to high. Had both ends of UQ cinched laid there and got CBS. Well i have heard others say they would draw the uQ up with some shock cord so had some already waiting if needed in my DIY Ridge organizer. Seemed to help for awhile but still a chill tucked the fleece throw under by but and helped some more. Now I feel that with my superfly with doors hung would have eliminated most of the draft I was getting from the missing man door. I don't have a undercover want to consider making a sock.
Also may get one of those heaver duty space blanket from coghlan's with the silver on one side and red material on the other may try to put in my double layer traveler silver side up as a vapor barrier I don't know. All I all I was happy I wasn't cold just chilled and only reason I slept poorly was frequent pee bottle breaks. Didn't want to cheat going in house for pee warm breaks wanted the whole effect .
