Responsible Down Standard

What's In Our Natural Down Duvet Insert?

Down & Wool Fill

The Natural Down Duvet Insert fill is a mix of 70% White Down with 30 % Wool. The Down meets the Responsible Down Standard (RDS) certification to ensure humane treatment. The Wool provides extreme breathability without adding excessive weight.

Premium Features

Each Natural Down Duvet Insert has a baffle box stitching construction to give the product loft, along with double stitched edges with German piping for durability. Additionally, we have included corner loops to tie to a duvet cover.

All Season Weight

We’ve designed our Natural Down Duvet Insert for all seasons - not too heavy for the summer, not too light for the winter. We achieve this by using premium fill materials along with the breathable cover.

Made in the USA of imported materials. Exterior Shell: China Down Fill: China and North America, Wool: Argentina and Chile

Organic Cotton

Our Natural Down Duvet Insert features highly breathable cotton fibers. The organic cotton we use is chosen for its ability to be soft and cool to the touch, yet comfortable due its sleek, tufted design. Our organic cotton fabric is also a great organic material with moisture-wicking benefits, keeping you cool and comfortable for a better night's sleep.
