80% Pure White Goose Down
Originated from the core down-producing areas of white geese - the abdomen, neck and wings, the natural down has a fluffy structure, which is scientifically matched with the flaky feathers to form an excellent warmth-keeping combination. As a high-end animal protein fiber, each goose down fiber is covered with a nano-scale triangular pore network. This precise structure gives it excellent temperature control properties, and can intelligently adjust the fiber gap according to the ambient temperature to form a dynamic temperature control system. When the heat energy emitted by the human body contacts the down layer, the pore structure can efficiently absorb the heat and form a heat cycle, while building a multi-dimensional thermal insulation barrier to effectively block the penetration of cold air and create a long-lasting warm wearing experience.
