Inspired by the great outdoors, made for the great indoors

The Casper duvet takes construction cues from performance outerwear to provide year-round comfort and warmth. Like your favorite jacket, sewn-through seams create small, rectangular chambers to help the naturally insulating down stay fluffy and in place. Plus, it’s built to last for years — just like our mattresses.

Down to a science

When it comes to insulation, duck down is the best temperature regulator out there. Plus, we love that it's humanely sourced.

Down Weight Illustration

Nice and light

You’ll never feel weighed down because the breathable cotton cover is thirty percent lighter than others on the market.

Duvet Seasonal Illustration

Never out of season

Forget about swapping or switching midyear — the Casper duvet is designed for comfort in any season.
