100% PURE HUNGARIAN GOOSE DOWN DUVETS DOWN is the soft, fine, under plumage of birds found beneath the tougher exterior feathers. Very young birds are covered only in down. Down is very resilient and a wonderful natural form of insulation as it has good lofting characteristics, trapping small pockets of air efficiently to provide a thermal barrier. This helps the birds to stay warm in the winter and cool in the summer. Feathers, on the other hand, repel water and keep the bird dry. Feathers also have a quill, whereas down is merely fluff and does not contain a quill. Genuine Hungarian Goose Down Duvets are the world’s finest filling. It comes from a country with subzero temperatures so its warmth retention is exceptional. It is also finer, lighter, and softer than any other Goose Down. Our luxury duvets are filled with 100% genuine Hungarian Goose down. To add weight and shape they are finished with luxurious Jacquard cotton and stitched in box construction to prevent the filling from redistributing. Hungarian geese come from a colder region of the world, thus making their down more thermal.
