80% Pure White Duck Down
Selected from the natural down-producing areas of ducks such as the abdomen, neck and wings, the down is in the shape of fine reed catkins, and feels soft and fluffy like clouds; supplemented by precisely proportioned flaky feathers, it forms a double-layer temperature-locking matrix. As a natural animal fiber, the ball-like structure of down is densely covered with hundreds of millions of micro triangular pores, which build an intelligent breathing cycle. When the body temperature rises, the fiber naturally stretches to release heat, and when the environment cools down, it shrinks tightly to lock in warmth. While efficiently recycling the heat dissipated by the human body, it isolates the invasion of cold air from the outside world and achieves 24-hour constant temperature protection. Light and imperceptible, it fits the body like a second layer of skin, making warmth and comfort seamless.
