I have a BA Blackburn UL that is like this. I actually really like it. Keeps me from sliding off the pad on a mild slope and works with just about every pad I've tried; some better than others.

One of my biggest price tag items has been my 0 degree down quilt+sleeping bag. Got is on sale; something like 350. Not the biggest splurge. It was the Big Agnes Lost Ranger 0* UL.

any of the 2 person Big Agnes UL Backpacking tents (buy used). Also any of the Big Agnes UL sleeping bags 0F Big Agnes does make a lot of UL (ultra light) gear...make sure to get a sleeping pad too, probably a folding foam sleeping pad is best (lightest and don't get pop)

I have a Big Agnes single I LOVE so I’m jealous of all the folks here with the double. We have a flatlands fleece double bag and the Klymit double pad because they were the easy buttons through our wedding registry. The bag packs large for my taste but the pad is perfect. We sleep on top of each other at home and love snuggling all the same in the wild. Unless your trips are all ultralight backpacking, it’s quite cozy and romantic!

I would go with a quilt, they are great for moving around. Zenbivy is most peoples favorite, I really enjoy my Big Agnes.

What you are describing to me just sounds like a poor quality fabric. Not all sleeping bags created the same. I love my big agnes also because of that inner fabric. Maybe try another brand? Otherwise a liner could help as well

If your biggest concern about a sleeping bag is room for your legs to move without feeling constricted, I would try out Nemo or Big Agnes sleeping bags. Both tend to have wider profiles. Definitely go for a bag that is rated at least 10 degrees lower - preferably lower - than the temps you expect to sleep in. Theres multiple problems with layering with clothing like this, one of which is not the warmth specific factor but the breathability. One or two layers is one thing, but with all the listed clothing and then something like the picture on top, you’re going to build up humidity near your body you can’t get rid of, and you’ll become even colder. Next, a sleeping bag basically creates a warm pocket of air around you. The insulation in the bag helps create and maintain this pocket. The more compressed this insulation, the worse it performs. With layering clothing, you compress the insulation, making it less effective. On top of that, insulation is minimal if not nonexistent at the seams. Some puffy jackets and “extreme temp” clothing gets around this by minimizing seams but there’s almost always a few somewhere, which means no air pockets and no warmth. If I could recommend the best case scenario for you, it would be this: find a sleeping bag you can tolerate rated to a temp appropriate for your conditions, 15F at a minimum, best scenario a 0F. Dress in only your smartwool layers, and make sure you have a good pad/sleep set up underneath you.

Just wanna say I respect the lack of overpriced fancy gear and I respect making it work for as long as you did! As much as I am “anti gear, pro getting out there”, a lightweight Big Agnes sleeping bag will roll up to about 1/8th the size of a rolled up Coleman. Mine has lasted me for 7 seasons so far no problems
