Nothing is better for sleep than a duvet made from real eiderdown. As part of the search for the best, most natural, most animal-friendly and sustainable eiderdown, Mama Hulda went on an expedition to Iceland. Mama Hulda’s sons discovered a real eider duck paradise on a remote peninsula. They were able to see the ducks raising their chicks, watch how the down is gathered and learn how the farmers process the valuable feathers.
