What Makes Our Duvet Inserts Unmatched?

We created a naturally down-proof fabric for our duvet shell by precisely weaving the highest-quality, 100% organic 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.

Comforter Extraordinaire
This comforter is everything Boll and Branch said it would be. Super soft, super warm and perfect for a cold winter’s night! Very happy we made this purchase!
Mid-layer is warmer than you think
The duvet is exceptionally fluffy and nice but warmer than I expected for a mid-layer.

Do it, you won’t regret it
Living in Arizona you want something fresh, not too hot. I will say I have had the duvet insert and cover for 2 months and absolutely love it. My husband appreciates our bed even more.
