This royal elite 650+ fill power lightweight down comforter is filled with hypoallergenic white duck down and covered with down-proof cotton. Natural duck down is perfect for providing warmth and proper insulation by wicking away moisture during sleep. It regulates body temperature to a comfortable level to improve sleeping quality. Four-way baffle box construction locks the down in each box evenly. This summer filing weight duvet brings the fluffy and cloudy sleeping experience. Comfort, Craftsmanship, Social Responsibility, and Traceability run deep in our blood. As a brand, Maholi is OEKO-TEX Standard 100, Responsible Down Standard (RDS), Global Recycled Standard (GRS®), and Canadian Down Standard (CDS) certified, and on top of that, we have been an active board member of the Down Association of Canada since our beginning in 1994. We track our sources and suppliers every step of the way to ensure our naturally luxurious materials come from ducks and geese that are treated humanely.
