According to the inquiry of Shencaotang Health Network, the goose down quilt is a kind of down quilt, filled with goose down cotton, and the real down quilt (goose down, duck down, etc. ) is the top grade in the quilt. Goose down quilt is characterized by good dehumidification and warmth retention. Goose down can absorb the waste gas and water vapor produced by human body through capillary action, and then quickly disperse it into the air, so people who often cover the goose down quilt not only sleep warmly, but also feel comfortable, dry and free from oppression.
