Enjoy the hypoallergenic, natural feather and down fiber blend comforter. We start with a super soft microfiber cover and generously fill it with a proprietary blend of 60% feather fiber, 25% down fiber and 15% feathers. You'll appreciate the 14 inch end-to-end sewn through boxes that will keep the natural fill from shifting--no colder spots. For added durability we've added a double stitched self-piping around the edges. Certified by the american down and feather council so you know you're getting a quality product. Contains RDS Certified Down: The goal of the Responsible Down Standard is to ensure the waterfowl in the down supply chain are treated humanely.
