Eiderdown is the exceptionally soft and insulating down from the female eider duck 🦢. These ducks pluck their own down feathers to line their nests, creating a cozy haven for their eggs. Eiderdown is prized for its superior quality, warmth-to-weight ratio, and rarity, making it more expensive than other types of down. It is carefully collected after the ducklings have left the nest, ensuring sustainability. Think of it as the cashmere of the down world 👑.
