I certainly wouldn’t call it sateen, and it got a tiny bit pilled in the dryer. But it’s still very soft, warm, and has a very comforting weight to it. I love that the exterior is 100% cotton and Thinsulate can’t be beat. I will most likely get a cover for this to preserve it but right now I’m using it on its own and it works great.. Emily.
