with a drawstring at the neck. Made it a foot longer and 6" wider at the shoulders, so that it fits a big guy, Now I can wear it as a poncho, stick out feet or arms at will, and it weighs a lb. Given clothing that's adequate for moving around at freezing temps, and a 10mg timed-release Ambien, the bivvy and a UCO candle lantern (beeswax candles ONLY) will let me sleep sitting up, at 20F, for at least 5 hours. That's all you need to keep going, and it rarely gets colder than that in my area. I can open the bivvy like a lean to for use with a Dakota fire pit, (hunk of aluminum foil radiating and projecting heat towards me, while hiding the light). Just before dawn, heat some rocks and water to get thru the early morning, In the afternoon, it's almost always above freezing here. That's the time to sleep, assuming that you're in thick enough cover. Add a couple of the mylar "tube tents" (worthless when used as intended) to wad up under my feet and butt, between my back and the tree that my torso is tied to, with the shemaugh and the bandanna bracing my neck, this setup works fine. When doing the lean-to thing, I stuff debris into the mylar bags and put one under the Bivvy, cover it with more debris, before deploying the opened-up bivvy over it. Then I use the remaining bag to block the end of the shelter that's facing the wind. This set up lets you handle 0F degrees, which is as cold as it ever gets here.
