Hung last night. No UQ. I don't have one. Did use HH's foam underpad and a "space blanket" I got at REI and modified with shock-cord attachments. So, the wind was blocked. On top I used my extra-large sil-nylon multi-purpose pack cover, also attached with shock cords.
I used my Exped 7.5 inflatable down-filled sleeping pad and my old Holubar sleeping bag (down, weighs 4 lbs 6 oz).
Wore socks, long-john bottoms, t-shirt and zip-turtle neck long-john top. Also balaclava, buff, scarf, and down hood.
Also I used a Nalgene full of hot water, wrapped in a t-shirt. Was still warm this morning.
Digital thermometer hanging on hammock chain from tree read a low of 5.2 degrees. Almost no breeze.
I was toasty all night. Here are some pics showing the space blanket attached to the bottom, the pack-cover over the top, and with the rain fly.
