Inspired by our favorite winter jackets, the Casper R&D team (the same one behind our award-winning mattress) created the down duvet for enjoying the great indoors. Designed for year-round use, the down duvet uses naturally insulating duck-down clusters to keep you comfortable and cozy. The carefully considered construction of the down duvet was proven to optimize your body's natural temperature regulation - keeping you comfortable from dusk until dawn. The rectangular chambers drape perfectly across your body, while the seams prevent any fill from migrating. Combined with our highly breathable outer cotton shell, the down duvet insulates your body without trapping body heat. Lastly, the down duvet was no different when it came to Casper's signature attention to detail. Discreet tags on either end help identify the head and foot of the duvet, while loops in each corner help keep it in place within your cover.

A lighter variation of Coyuchi's classic Three Season Down Duvet Insert, this airy option is designed for hot sleepers, warm climates, and those who simply prefer the modern look and feel of a bed with less volume. Filled with pure 600-fill-power down encased in a down-proof, 100% certified organic cotton shell with stitch-through box construction to keep the fill evenly distributed.

A naturally lightweight and lofty layer designed for year-round comfort. 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. The double-washed down is sourced from an Indiana duck farm where the birds are humanely raised, the down is carefully processed, and the quality is controlled from start to finish. We recommend this insert on its own for spring through fall, then layered with a blanket in winter for excellent temperature control.

This duvet is perfect. The loft is generous and evenly distributed. The down is very high quality and the cotton cover feels luxurious, even without a cover. I highly recommend this down duvet.. Anne I.. NL. Sun Nov 19 2023
