All of the fluff, none of the fuss

The Down Alternative Duvet Insert is your new favorite layer of cozy. Soft, breathable, and perfectly plush all year round.

Down-like comfort
The soft, hypoallergenic fill delivers that lofty, snuggle-worthy feel of luxurious down without the feathers or fuss.
Breathable by design
A 100% cotton shell promotes optimal airflow and helps regulate temperature so you feel “ahh” instead of “ugh.”
Smart structure
Box-stitching keeps the fill evenly distributed, while corner loops keep your duvet cover perfectly in place.

Stay in your corner

Four corner loops keeps your duvet insert locked into place inside the cover. No drifting, no bunching, no unauthorized movement.
