Spent last night in the backyard while the Mrs. slept inside pondering what kind of sense her husband really has. Setup consisted of WBBB Double 1.7, 3-Season Yeti w/ reflective liner, ccf and reflectix for the footbox, military poncholiner serving as a top cover, Superfly with doors on, fleece sleeping bag liner, and a 20* Mt Hardware synthetic bag. . . ok, ok... and my down pillow from inside. I wore lightweight thermal and mid-weight fleece pullover and 1 pair of SmartWool socks. After spending 15 minutes listening to the TCU -v- BSU game I checked the temp inside my hammock which read 48*. Outside temp at the time was 29*. I am convinced the top cover is a very good thing. However, I may have to go and get the BBO from Paul as the poncholiner, though it did well, did allow a draft in all night as the pullouts for the BB kept the liner just far enough away to allow that draft in one side then out the other. Slept warm all night and even tried out the hot water bottle trick for the first time and that was also a definite plus.
Now if I can keep the "hooligan" from coming into my backyard and pretending that he is a 120 lb rotweiler barking just outside my tarp, I just might be able to make it through the night with only needing 1 pair of thermals !
