What is "down"?
Down refers to a type of feather found in birds that is characterized by its smooth and fluffy texture. It is made up of soft, fine filaments that lack the interlocking barbs found in other feathers, giving it a delicate and airy appearance. The down feathers are typically located beneath the outer feathers, close to the bird's body, and serve several important functions. They provide excellent insulation, trapping air and creating a layer of warmth next to the bird's skin, which helps regulate body temperature in both cold and hot environments. The fluffy structure of down feathers also allows for efficient buoyancy, aiding birds in floating on water surfaces. Down is highly valued for its insulating properties and is often used in the manufacturing of bedding, clothing, and insulation materials.
