The rarest and finest down in the world, gathered by hand from the nests of wild eider ducks in Quebec.
The story
The eider duck plucks the softest down from her own breast to line her nest. At the Société Duvetnor sanctuary on the St. Lawrence River in Quebec, specially licensed collectors visit each nest by hand, take only a small portion of the down and replace it with straw. The ducks are never harmed and return to nest there year after year. Each nest gives only 15 to 20 grams of down, less than an ounce, which is why Eiderdown is so rare. Over 200 years ago the eider was nearly hunted to extinction for its down. Today this gentle, nest-by-nest collection helps protect the birds instead.
A wish sewn inside. An old Scandinavian tradition says that when a couple married, the bride's mother made them a down duvet by hand and sewed a coin inside for a happy, prosperous life. St. Genève carries on the tradition: every duvet has a coin sewn inside, a wish of health and prosperity from their family to yours. Each is hand sewn in their atelier in Richmond, British Columbia, by a small, specialized company with more than 50 years of experience in down.
Why it is special
- Eiderdown clusters cling together, forming an even, gap-free layer of warmth that feels almost weightless.
- It tests at 700+ loft but insulates like a 1000 loft down.
- Only a small amount is gathered from each nest, so supply is very limited.
- A portion of every sale supports the sanctuary's conservation work.
Choose your warmth
- Summer: For warm sleepers, warm bedrooms and mild climates.
- Classic: Our most popular weight. Right for most people, most of the year.
- Winter: For people who feel the cold or like a cool bedroom. Guaranteed warm enough.
Not sure? Choose the lighter weight. Down can be added later, but it cannot be taken out.
