Down Duvet Insert

$398 - $548


Build a bed that has incredible loft and near-weightless warmth with our carefully crafted down duvet insert. It’s filled with responsibly sourced down and wrapped in a soft, 100% organic cotton shell that naturally prevents poke through. The unique baffle-box construction keeps the fill perfectly in place for even fluff, while corner loops—which secure to the interior ties on our Duvet Covers—make it so much easier to make, and maintain, a beautiful and comfortable bed.

Available in three weights. Tailored for your climate and sleep preference.



Includes 1 duvet insert.
Featuring 650 fill power U.S. White Down with PurDown treatment.
