Three Season Down 600 Fill Power All Season Duck and Down

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.
