Simply the finest down comforter in the world. Upholding old-world European techniques in our Wisconsin facility, skilled artisans fill the St. Petersburg comforter with 850–900-fill-power Siberian white goose down—naturally hypoallergenic from our 12-step purification process—the loftiest, warmest, highest-quality down available. A sumptuous shell of German silk jacquard finishes the comforter in supreme decadence, while double hand-stitched sateen piping ensures heirloom-quality strength and durability. Offered in three weights for luxe comfort across every climate and season.
