Three Season Down Duvet Insert
Availability: In stock

A naturally lightweight and lofty layer designed for year-round comfort. Pure, responsibly sourced down is encased in a down-proof, 100% organic cotton shell. Stitch-through box construction keeps the 600-fill-power down evenly distributed. All Coyuchi down duvet inserts are made in the USA. The double-washed down is sourced from an Indiana duck farm where the birds are humanely raised, the down is carefully processed, and the quality is controlled from start to finish. We recommend this insert on its own for spring through fall, then layered with a blanket in winter for excellent temperature control.

If you tend to get cold at night, we recommend our Winter Weight Down Duvet Insert. Made with the same box-stitched, 600-fill-power pure down, it has more fill for a warmer, heavier feel.

  • Slightly oversized to lend our duvet covers an irresistibly lofty, cozy look.
  • Made in the USA.
  • Down fill is sourced in the USA; 100% organic cotton shell is imported form a GOTS certified facility in India.
In our mission to cut out plastic, this product comes in a reusable, organic cloth bag.

A down comforter will last many years if cared for properly. Always protect your comforter from direct contact with body oils by using a duvet cover or by placing between two flat sheets. Launder no more than once every two to three years unless there is obvious soiling; more frequent washing will shorten the life of your comforter.

Machine wash duvet in an oversized machine without a center agitator, using warm water and mild detergent on the delicate cycle. Check seams and fabric before washing; if weakness is evident, do not home launder. In order to fully dry the down clusters and to prevent mildew from forming, thoroughly dry on low heat well beyond the point where the outer fabric feels dry (approximately 3–4 hours). Place a couple of tennis balls or dryer balls inside the dryer to aid in the drying process. Air-dry for an additional 24 hours to release any moisture.

In between laundering, occasionally place comforter outside in fresh air and direct sun to restore freshness. Frequent fluffing will help retain loft.
