A lighter variation of our classic Three Season Down Duvet Insert, we designed this naturally airy option for hot sleepers, warm climates, and those who simply prefer the modern look and feel of a bed with less volume. Pure, responsibly sourced down is encased in a down-proof, 100% organic cotton shell. Stitch-through box construction keeps the 600-fill-power down evenly distributed. All Coyuchi down duvet inserts are made in the USA. Filled with double-washed down from an Indiana duck farm, where the birds are humanely raised, the down is carefully processed, and the quality is controlled to the highest standards from start to finish.
