This smooth and breathable sateen shell is filled with 100% Climate Beneficial™cotton. Designed as part of a coalition working together to evolve the way cotton is grown in California, every C4 purchase supports local farms and has the potential to restore the soil in our home state. A medium-weight, vegan alternative to down or synthetic fill, this batting is hand-tufted in a family-owned workshop in the United States. Your insert will arrive oversized and will shrink to standard size after the first wash. Due to the hand-tufted nature of this insert, batting may shift over time. We recommend drying thoroughly with wool dryer balls for best results. | Climate Beneficial Cotton Duvet Insert Full/Queen Undyed | Coyuchi
