Cloud-like comfort. Lounge, relax, or nap on this all-season comforter. Made with a polyester microfiber cover, this comforter is stuffed with 600 cubic inches of down-filling made from goose feathers and fibers. It features a baffle box stitch that evenly distributes the down across the comforter, ensuring even warmth and padding across your bed. We love that it comes with duvet ties at the corners, making it easy to slip into a cover of your choice (sold separately). To care for it, just machine wash and line dry.
