According to Baidu Aigou, down is a natural filling material, which is collected from wild or domestic poultry, including ducks, geese and swans. White duck down is a kind of high-grade down collected from the abdomen of a waterfowl called white duck. White duck down has better warmth retention than ordinary down. Because the white duck down comes from the belly of the white duck, the belly and other parts of the fluff come from the same source, which can ensure the purity of the filler. White duck down has finer fineness, more uniform gap filling and better warmth retention. At the same time, white duck down has a higher density and can keep warm at a lower temperature. Therefore, white duck down is good.

White duck down is warm, soft and comfortable, light in weight, breathable, white and warm. However, both of them belong to down filler, but white duck down is usually more upscale than ordinary down due to its advantages of source and warmth. At the same time, when choosing clothes or bedding, you can choose the right material according to your personal needs and budget.
