A word or two on quilts...
Some folks love them, but when I did a comparison, for me they didn't make the cut. No doubt they work great for some. I found that the notion that they were lighter because there is no insulation under you didn't actually hold true in the ones I compared because they needed more size to not have drafts under the edges.

Then there is the adjustability of a quilt. I find that I do the same thing with a bag by zipping it open and using it like a quilt when it is warm and progressively, climb in, zip up, use the hood, and pull the hood tight with only a small hole to breathe through as it gets colder.

Given all that I found that my Mountain Hardware Phantom 45 was comfy for a super wide range of conditions, was lighter, and packed as small. It packs to about the size of a water bottle and weighs a little over a pound (mine is 17 ounces, but the current model is listed at 19 ounces). Add two pairs of socks and one layer of clothing and I am good down to the mid teens or so. I have not found a quilt that matches that size, weight, performance, or flexibility.
