Casper Sleep Down Duvet, King/California King, White


Inspired by our favorite winter jackets, the Casper RD team the same one behind our award-winning mattress created the Casper Down Duvet for enjoying the great indoors. Designed for year-round use, the Casper 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 ’til 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. Complete with a 1-year limited . Machine wash cold on a gentle cycle with like colors. Tumble dry low.
