I’ve been trying to find an opportunity to test my gear at cold temps. I just went on a trip where it was 14 F. Pretty calm winds.
My coldest time is when I get up in morning and make some oatmeal, coffee, and tea. The worst problem is my fingers get cold. As my torso and head get cold, blood to fingers is restricted. If I have enough torso and head insulation it’s easier to keep my fingers warm.
I was wearing supplex shirt and pants, 3.5 osy apex pants and jacket, 9 ounce down vest, and long WPB jacket on the outside. Fleece fingerless gloves. Fleece hat. I was quite warm – I could have gone down to 10 F or less.
The next morning it was 18 F and I swapped out the apex jacket for an apex vest. I was warm enough but close to my lower limit.
Someone posted a video of IR of someone sleeping in a quilt. The biggest thing I noticed was the head was glowing like a light bulb. That is where most of the heat was being lost. So I’ve tried a couple things.
A scarf is a good idea but sort of heavy, so I made something out of 0.7 osy nylon and 3.5 osy apex. Rectangular, with tapered ends, and closed on the back with velcro. 0.9 oz:

and I added some side flaps to a fleece hat. 2.5 oz:

Wearing them:

That’s pretty good, but not a huge amount of insulation with fleece, so I made a hood with 0.7 osy nylon and 3.5 osy apex. 1.9 oz:

wearing it:

I wore that at night sleeping but I didn’t like how it touches my mouth. So I took it off. I need to work on this, maybe just cut out the ends of the flaps so it doesn’t touch my mouth
