なぜアイダーダウンが世界で最高なのですか？

A Natural Marvel. A Luxury Without Equal.

When it comes to down insulation, no material compares to Canadian eiderdown. Often referred to as the gold standard of natural fill, eiderdown is coveted by luxury bedding and outerwear makers around the globe—and for good reason.

At Atelier Olmsted, we use 100% ethically sourced eiderdown as the core of our performance-luxury outerwear. Here’s why it’s not just better—it’s the best.

1. Rare by Nature

Eiderdown is among the rarest natural materials on Earth. It is collected by hand from the nests of wild eider ducks, which live in remote Arctic and sub-Arctic coastal regions like Northern Quebec and the Gulf of St. Lawrence.

Because eiders are a protected species, their down can only be harvested under tightly regulated conditions, and only after the ducklings have hatched and left the nest. This ensures a cruelty-free, sustainable, and highly limited supply—making eiderdown more exclusive than gold or cashmere.

2. Unmatched Warmth Without the Weight

Eiderdown's thermal efficiency is legendary. Its clusters are larger and more elastic than other types of down, allowing it to trap more air and create a superior insulation barrier—even in extreme cold.

At the same time, eiderdown is astonishingly lightweight and compressible, giving you maximum warmth without bulk. It’s the perfect insulation for outerwear that must perform in sub-zero temperatures without sacrificing elegance.

3. Naturally Hypoallergenic

Unlike synthetic fills or lower-grade down, eiderdown is naturally resistant to dust mites, bacteria, and other common allergens. Its lack of sharp quills and chemical treatments makes it ideal for allergy-sensitive skin and respiratory health.

Some users even report a calming effect from sleeping under or wearing eiderdown—a result of its breathability and thermal regulation. Whether you’re layering for the outdoors or winding down for sleep, eiderdown supports both comfort and wellbeing.

4. A Material That Deserves Mastery

Because eiderdown is so rare and delicate, it demands exceptional craftsmanship. At Atelier Olmsted, every coat is designed, cut, and sewn in Montreal, and each piece is filled with traceable Canadian eiderdown—guaranteed for quality, performance, and ethical origin.

Our coats are built in limited runs, reflecting the exclusivity of the fill and our commitment to slow fashion and sustainability.

Excellence, Elevated

Whether worn through winter storms or admired for its refinement, eiderdown remains the pinnacle of insulation. Its rarity, softness, warmth, and health benefits make it a defining material in the world of ethical luxury—and the core of every Atelier Olmsted creation.
