White duck down itself produces grease, which quickly dissipates after absorbing moisture. Therefore, duck down has excellent moisture-proof performance. Thousands of air holes are densely covered on the ball-like fibers of duck down, which has the function of moisture absorption and dehumidification to keep the product dry all the time.
Down is sustainable, environmentally friendly and the most comfortable natural thermal material. The market for down products has always existed, so the production of RONGDA down and feathers will be permanent.
