90% Pure White Duck Down
Originated from the duck's abdomen, neck, wings and other high-quality down-producing parts, the down presents a natural reed-like clustered shape with excellent fluffiness; supplemented by precisely proportioned flaky feathers, it builds a three-dimensional temperature-locking structure. As a natural animal protein fiber, the down ball structure is densely covered with millions of nano-scale triangular pores, forming a dynamic breathing system. When it is hot, the fiber stretches to release heat energy, and when it is cold, it automatically shrinks to lock in warmth. While efficiently absorbing the body's dissipated heat, it blocks the penetration of external cold air to achieve all-weather intelligent temperature control. Light, soft and warm, close to the body without pressure.
