Eiderdown, more valuable than gold


Eiders live in the most inhospitable of all landscapes. The bare chicks have to survive, surrounded by bitterly cold polar storms. Anyone who has ever weighed eiderdown in the palm of their hand will be amazed at its mysterious aura and a thoroughly skin-friendly feeling. 


The eider lives mainly in Scandinavia, North America and Iceland in the wild and is under strict protection by farmers. The duck plucks the down itself to warm and cushion the nest for its brood. The down is much more delicate than conventional down and so light that you can only feel a handful of feathers with your eyes closed when your hand becomes warmer.
