The rarest insulation on Earth. Gathered by hand.

Eiderdown is gathered from the nests of the eider ducks, a process rooted in patience, not plucking. Each kilogram takes hours to clean by hand. The result? A naturally hydrophobic, hypoallergenic, ultralight, silent material with unmatched insulation-to-weight ratio. The Primus Inter Pares. There’s nothing like it. And never will be.

A thousand years of keeping Iceland warm.

Eiderdown isn’t made. It’s entrusted. For generations, Icelanders have guarded the wild eiders and gathered its down — not by force, but through coexistence. This is the legacy we inherit, evolve and pass on.

Not farmed. Not forced. Not compromised.

No greenwashing. No half-truths. Just the quietest, most sustainable insulation story in the world.

Nature trusts us. We return the favour.

No cages. No compromise. Just care.

The world’s highest quality insulation in harmony with nature.

1

Nesting Season Begins

Our family prepares the nests for the arrival of the ducks at the start of May each year. This involves cleaning out nests, fencing the sanctuary off as well as decorating our sanctuary to indicate that this is a safe place to nests for the ducks.

2

Incubation

The ducks lie on their eggs for approx. 25-28 days and will lose around 30% of their body weight while doing so. During the nesting period, the ducks naturally molt their eiderdown, which they have used to stay warm during the Arctic winters around Iceland. This process allows the ducks to keep their eggs warm as the eiderdown is so insulating it wouldn’t allow them to exude their warmth to their eggs.

3

Down Gathering

Just hours before the duckling’s hatch, we go around the whole sanctuary and gather the leftover eiderdown. This process involves immense care and respect for the birds as to not disturb them during this vulnerable stage of their breeding process.
4

Hand-Cleaning & Sorting

After the eiderdown has been carefully gathered it is then taken for drying and initial cleaning, followed by sterilization at 130°C for four days. The down then goes through a machine cleaning process and finally a hand feather clean and hand wash. This ensures that every gram of eiderdown has been carefully selected and surpasses all standards. Our whole process, from nest to product utilizes 100% renewable energy.
5

Testing & Quality Control

To ensure that our quality is consistent we apply the Eidermark ™ standard. Eidermark ™ is the only standard of its kind as it only applies to wild and ethical Icelandic eiderdown that has passed the strictest quality control of any insulation material in the world. This ensures that our customers receive the best insulation in the world, ethically and sustainably, every time.

Product Creation / Export

After cleaning and quality control the down goes to three places. It gets put into our bespoke, custom-made duvets. It goes to our outdoor brand Ducking Warm where it gets put in the most rugged outdoor gear on the planet. Lastly, we ship eiderdown to our collaborative partners all around the globe. Our partners have entrusted us to provide them with the highest quality insulation on the planet for decades.

The Pinnacle of Sleep

Icelandic Eiderdown Duvets — Nature’s Rarest Luxury

THE PINNACLE OF SLEEP

Icelandic Eiderdown Duvets — Nature’s Rarest Luxury

Inside the World of our Icelandic Eiderdown Duvets Some objects in life are simply too rare and complex to be replicated, too refined to be mass-produced. Icelandic eiderdown duvets fall squarely into that category. Passed down through generations like heirlooms, these extraordinary duvets represent not just comfort, but legacy.

To put their rarity into perspective: eiderdown is six times rarer than natural diamonds. And while the world marvels at the craftsmanship and scarcity of a Rolls-Royce, around ten times more of those are made each year than eiderdown duvets. This is a product not for the masses, but for those who seek the pinnacle of sleep, of stillness and luxury without ostentation.

But rarity alone isn’t the story. The magic lies in how eiderdown behaves. Gathered from the nests of the wild common eider duck of Iceland after they’ve finished using it, the down has a natural ability to expand and contract with the ambient temperature. It keeps you at a perfect Goldilocks state, never too hot, never too cold, regardless of the season. And unlike other types of down, it does this without weight. Our duvets are so featherlight, they feel more like a soft breath than a blanket.

For over 80 years, our family has been in the business of crafting 100% pure Icelandic eiderdown duvets, no blends, no fillers, just nature at its most refined. Every batch is rigorously tested and certified hypoallergenic, making our duvets suitable even for most people with down allergies.

In a world that often rewards speed and scale, we choose patience and perfection. There is no fabricated scarcity, what nature provides is all we can get. Eiderdown can only be gathered once per year and supply depends entirely on nature. And those who discover eiderdown, often do the same.

Every Icelandic Eider duvet is crafted only after you reach out. There’s no stockroom, no conveyor belt and certainly no rush. Each duvet is hand-filled and sewn in Iceland using 100% wild eiderdown, no blends, no compromises. Encased in 800 thread count, 100% sateen-woven cotton, these duvets are exceptionally light, strong, and built to last generations.

Certified by the Eidermark standard and tested by IDFL, each duvet carries our promise of quality, sustainability, and integrity.
