Is the Warmest in the world

Canadian Eiderdown

Eiderdown is the rarest in the world. It’s unique high density and clings makes it the highest insulating and most luxurious down in the world. Eiderdown has incredible breathability, its insulating capacity is so advanced that it adjusts to the body’s temperature. 

Collected by hand from the nests of wild eider ducks, no bird is harmed in the process. This limited, sustainable harvest helps protect nesting habitat.

While promoting biodiversity

Olmsted's eiderdown is hand-gathered by Societé Duvetnor, on the protected islands of the St. Lawrence Estuary in Québec. While having a significantly lower carbon footprint than synthetics and other downs, this genuine Canadian eiderdown literally contributes to the protection of biodiversity.

In Québec, the sustainable harvest of eiderdown has allowed the non-for-profit Societé Duvetnor to purchase, protect and enhance several islands of the Lower St. Lawrence. This method also yields detailed scientific information about the status of the population that is used by biologists to manage the species and its habitat.


Its unique high-density and cling, means it insulates at a much higher rate, surpassing its 700 fill power. In a puffer coat, down that holds together at all times will evenly fill the entire channels without leaving spaces through which heat can escape.

Higher Loft

Eiderdown has extraordinary elasticity and resilience making it incredibly durable. Eiderdown will resist the test of time. Containing no feather, it can be compressed repetitively and still recover its initial volume, meaning it never loses its lofting capacity.

Advanced Breathability

Eiderdown has incredible breathability, with an insulating capacity so advanced that it adjusts to your body’s temperature. Marvellously well adapted for high-end outerwear, eiderdown breathes, letting body moisture escape.
