Any natural fiber you use will be breathable. I agree the W&N is very heavy (but what I use all the time). I have not used it, but a friend uses the Quilter's Dream 100% cotton all the time. It, too, has a lovely drape. I'm in the same boat as you with the night sweats but I still like a heavy blanket/quilt on my bed. I currently have a heavy 100% cotton quilt; 100% cotton blanket as well as sheets. Even at the muggy 65 deg. nights we had here recently, I still used anywhere from all to none of those layers during the course of the night.
