Down is the light fluffy coating clustered beneath the feathers of waterfowl that helps to protect them and keep them warm through natural insulation. Down is a three dimensional cluster made up of fluffy filaments and contains no quill.
Feathers are from the plumage of waterfowl, and do contain quills. They are two dimensional and provide insulation and support to down and feather products.
Down and feathers provide us with natural fill products that are breathable, durable and resilient, and provide excellent insulation without a lot of weight. Down and feather products are also natural and environmentally friendly; their manufacture leaves a far lower carbon footprint than synthetic materials.
