Down is defined as a unique three-dimensional cluster with the ability to trap air and add warmth without weight. It's breathable and wicks away moisture while insulating. All of the down and feathers used are sent through a proprietary cleaning and sterilization process, making the down hypoallergenic. The shell is made of a 100% cotton, down-proof fabric in a baffle box construction, keeping the fill evenly distributed. The warmth level of this all-season duvet insert is mid-weight, ideal for any time of year or climate.

That plush feeling you get from actual down translates to this thoughtful alternative made from a 2.2 Denier Polyester cluster fiber that's especially appealing to individuals with sensitivities to down. Manufactured in Grand Rapids, Michigan, they're made in small batches by artisans dedicated to meticulous craftsmanship. The shell is made from a soft 100% cotton fabric in a baffle box construction for optimal sleeping comfort. This option fits standard Twin-sized duvet covers.
