One simple step to light and lofty bedding bliss. Our 100% pure down is sourced from an Indiana duck farm, right here in the USA. The birds are humanely raised, the down is carefully processed, and the quality is controlled to the highest standards from start to finish. Double-washed fill is encased in a down-proof, 100% organic cotton shell, with a stitch-through box construction that keeps the fill evenly distributed throughout the duvet insert.
