Especially eiderduck down are of high quality. They come from the species eiderduck that are living as protected birds in the wild on the coasts of the Northern Seas. Eiderduck down must be picked from the abandoned nests after the breeding period.
They provide excellent fill power figures which almost double the fill power values of top-quality goose down. One kilogramme contains about 500 000 single eiderdown but only 300 000 goose down. Eiderduck down are even more delicate and lighter than goose or duck down and have a natural brownish colour. They have scarcity value and are difficult to process, respectively, which leads to stiff prices.

Eiderducks mainly live in Iceland, Greenland, Scandinavia and the Northern regions of Canada. They breed in hollows on the ground or on rocks and pad out the nests with down they plucked out from their bodies themselves.
Eiderducks are protected birds since they are a critically endangered bird species and cannot be bred.

After the young birds left the nest the eiderdown are collected. Only personnel that was well technically trained, is permitted to climb on the rocks to pick the down from the nests after the breeding period. Thus, there is tight supply, but great demand (Saudi-Arabia, Japan).
Eiderduck down have excellent heat-insulating capacities. The barbules are larger than goose and duck down and have countless ramifications. In spite of their size they are even lighter and more delicate than usual goose or duck down. The barbules of eiderduck down are twinned. Their barbs are frizzed and form prongs at their ends which make the down stick together. If they did not form a cohesive pad, the wind would blow the single down out of the nest.

The sticky structure of the eiderduck down makes the processing difficult. Bedding articles filled with eiderdown have to be cleaned and processed manually.
