EIDERDOWN: A Gift from The Eider Duck... At CASTELLO, we uphold the utmost care and respect for nature's gifts. In the crafting of our products, there is no physical contact with the Eider Duck. The Eider Ducks naturally molt, graciously leaving behind the precious Eiderdown in their nests for ethical harvesting by the farmers.
Additionally, our Silk Shells boast a thoughtful design that resists odor and moisture retention, guaranteeing longevity for future generations to cherish and enjoy.
 
Purchase includes our 10 Year Warranty.
 
FACT: There is approximately 4,000kg of Eiderdown produced each year. Iceland accounts for approximately 75% of that total and our farmers’ Eider Ducks provide between 35-45kg each molting season. Arguably the most valuable commodity in today’s marketplace.
