If you go to the Hobbs batting website (follow this link --
http://www.hobbsbatting.com/our-products/ ) on the right hand side is a .pdf symbol. Click that to get a comparison chart of the various battings that Hobbs produces and sells. The company is located in Waco, TX, and tries as much as possible to use materials that are grown or raised in Texas -- cotton and wool. I don't know where they get their silk from. So if "made in the USA" is important to you, this is the product to buy. And no, I don't work for Hobbs. Their silk batting is highly recommended for jackets, because it drapes so nicely. And they just came out with a new product that is a wool/cotton combo batting that is supposed to be very nice. Haven't seen it in any of the stores I frequent yet, but I keep looking.
