Here is the full picture, didn't give all the details in my post showing interest...
The pads are actually to supplement a 20 deg 3/4 UQ, I have 5/8" total in thickness of CCF. Plus put together a wider bit of reflectix to help with cold shoulders. I have a sock for the hammock, and doors on the tarp. Plan to trench in the tarp to help trap a little more heat and reduce convection loss. 1.7 DL hammock to help keep it in place, along with an extra-wide 0 deg top quilt from UGQ at 56" in ensure I have enough tuck. Packing in some extra long underwear, basspro 1.0 and 3.0 baselayers along with UA basemap and base4.0 which all fit over each other nicely - not as many layers for the legs. For heat I've got 3x SS water bottles that I trust not to leak to be filled with hot water, and packing in lots of chemical heaters as well just in case. Almost forgot GoLite's warmest hooded down jacket. And the weather guess is favorable (always still unpredictable) at lows in the teens with daytime highs getting close to 40 (t-shirt weather).
Sadly I just found out Tuesday that my UQ wasn't going to arrive in time, and when I asked if my pads only would leave me freezing and for any other last minute insulation suggestions I received two very generous offers of loans on the same UQ (yeti) that I am awaiting delivery in both 20 deg and 0 deg versions. Thanks again to OutandBack and Rhinoman!
And now a thanks to Bosman for looking out for me as well! I am still amazed that I haven't seen any flames or hatred on here, everyone is so very helpful and friendly compared to most other boards I've been on. The others are mostly tech boards for work, so I guess all that built up stress and angst shows quite a bit more over there - they need to get a hammock and get outside to relieve that! This is a great community of people and glad to have been able to start joining in.
Given this is my first cold weather hang trying to go over prepared, always seems like a better option than under prepared to me. Still would like to get some wider pads long term
even if I end up with an overstuffed full length 0 deg UQ, mainly for the ability to go to ground in high wind. Going to have to get a pulk at this rate as well cuz snow shovel, snow shoes, and extra wide pads just aren't going to be great all strapped to outside of pack
