Nice rig! *I like that tarp*. - and judging by that wind speed I bet you did too!

Sounds like you're using a nicer version of what I use to get down around the -10C range or so. although it sounds like you've still got some room to go colder. I've slept in mine with a 2 inch or so layer of poly batting next to the hammock bottom, 3 crinkled up space blankets below that, and my silponcho holding the whole "underquilt" on the hammock. Inside the hammock I had 1 and a half 27 wide inch blue foam pads (the extra under my butt). wearing long johns and full fleece (200wt) to bed, and a -10C rated down bag used quilt style, I slept good, but I didn't shed any layers.


I didn't think it got that cold way down there
