And check out the Hobbs website.
http://www.hobbsbatting.com/our-products/ On the right side of the Products page, they have a comparison chart of all the batting types they make.
I don't work for Hobbs, but I like their Tuscany silk and wool batting.
Remember that natural fibers (cotton, silk, wool) "breathe" and all of them make good batts for lightweight quilts.
