What Makes Our Duvet Inserts Unmatched?

We created a naturally down-proof fabric for our duvet shell by precisely weaving the highest-quality cotton threads. With our bafflebox construction, we turned fill density into a science, tailoring the exact amount of down fill needed to support your climate and sleep temperature.

Down Without the Downside.

We partner with farms in the U.S. to ethically source the finest, cruelty-free down fill that's IDS certified—requiring that all down and feathers are inspected and tested by IDFL to ensure each step of production, from farm to finish, meets the highest standards of quality and animal welfare. We triple-wash our down and feathers to be 2x cleaner than the U.S. government standard, using the highest-grade, environmentally-safe chemistry to guarantee a cleaner, longer lasting loft.

Beautifully made & fits well
I’ve tried another brand of insert and it never fit well. This one is fluffy and very nice in my Boll & Branch Duvet

Light weight still super cozy!
I read other reviews and went with the light weight. It’s perfect! It still feels lofty and cozy! I’m sure a heavier weight would be great for a chilly winter, but right now I sleep hot and the light weight is perfect.

Wonderful Down Duvet Insert
The medium is delicious and so well-made. Enough warmth for our summer air-conditioned bedroom and I'm thinking it will be perfect for the autumn and winter. The quality is superb. B&B products never let me down. we have everything from King size bed to towels and of course your sheets and duvet (now) as well as covers. Thank you!!
