Made with 600-fill premium white goose down, one of nature's best insulators, for lightweight warmth. Repeated washing makes our down hypoallergenic, far exceeding government standards. The soft 280-thread-count cotton cover is 100% downproof. This midweight comforter offers softness and warmth year-round. Permabaffle gate system guarantees down will not shift. Baffle-box construction helps fill retain volume and full loft in each chamber for uniform thickness and fewer cold spots. USA, materials imported.
