I've used a couple of brands , enlightened equip. , jacks are better , Kifaru.
I don't like the air leaks and by the time you use straps to keep the quilt close to the body, well I would prefer just unzipping my WM bag and using that as a quilt.
Lots of people like them but I move around too much for them to be practical.
I kept the jacks are better for an under quilt with my hammock.
