アイダーダウンの魔法、地球上で最も暖かいダウンの撥水性を探求する。

The Magic of Eiderdown, exploring the hydrophobic qualities of the warmest down on earth.

As the seasons change and the weather gets colder, many of us start to think about ways to stay warm and cozy. One of the most effective ways to do this is by using the most luxurious down, collected from the Eider duck. While Eiderdown products can be expensive, their superior performance and luxurious feel make them a worthwhile investment for those seeking the ultimate comfort and warmth.

Eiderdown and its Hydrophobic Qualities

The term "hydrophobic" originates from two Greek words: "hydro," meaning water, and "phobos," meaning fear. In the context of chemistry and material science, when something is described as hydrophobic, it means that it repels or does not easily mix with or absorb water.


The Eider duck is a large sea duck that lives in cold, wet environments in North America. To survive these harsh conditions, the Eider duck has developed feathers with unique properties that help it stay dry and warm.
The feathers of the Eider duck are coated with a thin layer of oil secreted by the duck's sebaceous glands. This oil makes the feathers water-resistant or hydrophobic, which means that they repel water. When the duck is in the water, this hydrophobic layer prevents water from soaking into the feathers and causes water droplets to bead up and roll off.

The hydrophobic properties of Eiderdown make it an excellent filling material for duvets, jackets, and other outdoor clothing. It provides excellent insulation, helping to keep you warm and dry in cold, wet conditions.
