Eiderdown is naturally hydrophobic. The unique structure of the eiderdown feathers helps to create tiny air pockets, which trap air and provide excellent insulation. Additionally, the outer layer of the feathers contains a waxy coating that repels water, making eiderdown resistant to moisture.
Eiderdown is gathered from the nests of the common eider duck. These tough ducks stay out at the rough seas around Iceland year round as they don’t migrate. In order to survive the Icelandic winters they insulate themselves with the eiderdown. When they start nesting each spring the naturally moult their down due to hormonal changes. This is done so they can keep the eggs warm and brood the eggs. If they wouldn’t moult their down they wouldn’t be able to get their body warmth to the eggs as eiderdown is so insulating. We then go around and gather the down from the nest of the ducks just before the eggs hatch. We do it just before the eggs hatch because the ducklings leave their nests within 24 hours of hatching and after they leave the down blows away.
