Supremely fluffy down clusters providing exceptional quality and re-loftability. More down clusters mean more fluffiness and more insulating warmth. A Down Cluster is the group of components: down (cluster), nestling down (a very immature feather or down that comes together at tiny quill point), and plumule (soft, fine feathers where the central shaft is as fine as the filaments that come off of it). This cluster is 15% higher than the industry standard at 75%. Featured in our Lunesse Comforter™.
