Egret YF 30

I’m a smaller lady and I found getting a women’s sleeping bag to be a game-changer. Lighter because there’s less of it, cut in a way that accommodates my body, warm in all the right places - especially the feet! I got the Feathered Friends Egret YF 30, not cheap but not $1k, and it’s my best friend out there. It’s kept me warm even on windy and snowy nights, and it’s so comfy I look forward to backpacking. You’re getting a lot of advice to look for quilts, which is valid from a weight tradeoff perspective, but I personally find them a bit fiddly to set up at the end of a long day - I prefer a mummy bag, and the Egret is plenty light for my purposes

My feathered friends egret is one of my favorite things I own. Having the toe box in the right place makes all the difference. I got the 30 yf and I’ve not been cold in it yet

I'd been using a Marmot for 30 yrs, what they called a 10-20 30. Don't remember the price but it was the most expensive thing I bought for a very long time and glad I did. There were not as many choices back then and I don't think they are the same now. Point is it was annoying when it was warm. Couple of years ago I got a Feathered Friends Flicker 40. It's a hoodless sleeping bag that can also open all the way to a quilt. (no it doesn't attach to a pad) Had that down to mid 30's cowboy camping in the desert and was fine with a puffy on. I had wanted a 30 but out of stock. This year sold the 40 and got a 30 for a trip to Iceland in July. I'm very happy with it; works well across temps. Combined with the Marmot gets me down to 0. Since it is a bag when I want it's less fuss than a lot of the quilts out there. (love the draft collar and the foot closing completely). You can rent one and they will credit up to 2 nights rental cost toward a similar purchase. May help but likely incur some extra shipping costs unless you're in their area.

Feathered Friends has short bags for women. Temp ratings are spot on. The YF bags save $ over the UL for very slight weight increase. They also have a kids Flicker; 5ft hoodless bag that can unzip to quilt. I have a regular YF 30 that I love. Worth a phone call. 

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

Western Mountaineering, Feathered Friends or Marmot for bags. Enlightened Equipment, Hammock Gear or Katabatic for backpacking quilts. Not cheap but quality and comfortable.

I've been a quilt user for years, but if I were looking for sleeping bags, I would go with either Western Mountaineering or Feathered Friends. You absolutely get what you pay for with either brand. Awesome quality.

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.

Really high end would be Feathered Friends or Western Mountaineering, basically life time bags. If you are in Europe Cumulus is a great alternative.

The ratings are not always reliable so you are right to be uncomfortable with them. One good baseline is ounces of down at the same fill power. Comparing bags that way gives you a better comparison point. Western Mountaineering and Feathered Friends are generally reliable in their ratings. That should give you an excellent place to start.
