Down Alternative Duvet Insert



Enjoy an alternative that offers the closest feeling to down, with this carefully crafted duvet. It’s filled with PrimaLoft™—a premium, allergy-friendly fiber—and wrapped in a soft, 100% organic cotton shell. Its 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.
The loft and experience of our down alternative duvet insert is engineered to be comparable to our down duvet inserts.
