Have you looked at Feathered friends bags? I have the Egret yl 20°.
I thought that I was a cold sleeper until I upgraded my sleeping bag and got one that is the proper length (I am 5ft5 and got a women sleeping bag for 5ft6 women). It made an incredible difference in how the sleeping bag keeps and uses my own body heat. I got the Feathered Friends Egret 20 yf. I pair it with a Big Agnes Rapide Sl pad and it is now my preferred piece of gear!
My SO sleeps cold. Thermarest Trail Pro - they used to make a women's specific one. I may upgrade this to the Nemo Tensor All Season for a holiday gift. Feathered Friends Egret - I take this from her when I go climbing it's so cozy I sleep warm- I freaking cook: Nemo Tensor All Season EE Enigma 30 950 fill
I paid $1k for a -40 degree sleeping bag. Because the -20 degree sleeping bag I bought the year before wasn’t warm enough. Feathered Friends. They are $1,200k now. Alaska is cold in March.
Western Mountaineering, Feathered Friends or Marmot for bags. Enlightened Equipment, Hammock Gear or Katabatic for backpacking quilts. Not cheap but quality and comfortable.
There isn’t really an absolute best, but I like Katabatic for a quilt and western mountaineering or feathered friends for a bag. I prefer quilts down to around the low 20s, bags below that. Having a pocket in your quilt for a sleeping pad seems silly to me.
At those temps you don't want to be messing around with some (relatively) unknown brand. I would also go insane if I had to deal with some fiddly hood that let in drafts around my neck in the winter. As far as I'm concerned, in the winter you have two options -- feathered friends or western mountaineering.
For sleeping bags I do Feathered Friends. PHENOMENAL products. Carefully selected down feathers and they don’t have to kill the animals to get them. I’ve got 3 different Feathered Friends sleeping bags for different temperatures, including an ultra thick one that I’ve used alone sleeping in no-tent self-dug snow trenches in the middle of Yellowstone in January. The outer layer of the sleeping bags is synthetic, but the primary ingredient is natural feathers. I also have one of their down packable jackets, but it’s too hot, even in -20F. Last time I camped in deep snow for a week, alone, on cross country skis, pulling all my gear on a Fairbanks siglin pulk sled behind me, I found I didn’t need much during the day, because I was working so hard I was always hot. At night I would dig a trench, lay a tarp across the top, supported by my ski poles, and sleep in my FF down bag on top of a thermarest. I’d keep my boots in the bottom of the sleeping bag so they didn’t freeze overnight. Wool socks, wool long underwear, wool sweater, synthetic wind-and-snow protecting pants and jacket. Wool hat, neck gaiter, and gloves. Synthetic outer-layer for gloves to keep my fingers drier. Smartwool makes merino wool boxer briefs. You need less than you think. (Except calories, holy f— do you need a lot of those.)
