The Nanga Down Cycle

A four-part introduction to Nanga's recommended down product life cycle

The down used by Nanga begins as high-quality, unprocessed, imported down. It is then cleaned and processed by a Japanese domestic down manufacturer, before being made by Nanga into finished products. These products can be used anywhere, from in town to the great outdoors. Their lives can be extended with proper care. When a down product is finally worn out, a recycling project allows that down to be brought back to life as a new product. Here, we would like to introduce Nanga's recommended down product life cycle in four parts.

What part of the bird's feathers does the term "down" refer to? The ins and outs of down

The term "down" refers to the feathers that grow on the breasts of water fowl. Down is light and offers great insulation, along with the ability to pass moisture into the atmosphere. Balls of down are known as "down clusters." Down is a precious material. It can be collected only in small quantities from a single bird, and is not found in land fowl. It is only found in water fowl, which live in waterside areas and need protection against the loss of body temperature. The down that is used as a material for manufactured products comes primarily from two kinds of water fowl: geese and ducks. Goose down is large. Its fine, soft fibers provide excellent insulation and water absorbency. In contrast, duck down is firm and flexible, which gives it great resiliency, making it ideal for use in products that need some springiness.

Kawada Feather, Japan's leader in making beautiful down

The down that Nanga uses in its products is cleaned and processed by the down manufacturing company Kawada Feather. Unprocessed down from water fowl can be covered with dust and dirt that is invisible to the naked eye. When this dust and dirt comes off, it can lead to a decrease in the down's insulation ability, as well as the appearance of bacteria and mites. Kawada Feather's main factory is equipped with purification and processing equipment of the company's own design. The factory is located on the Ise Plain in Mie Prefecture, Japan. The pristine water provided by the beautiful, mountainous environment is a key factor in the process of cleaning the down at this factory. The dry air causes the down to expand, which further improves the factory's ability to remove the dirt. The water is clean and extremely soft, which makes it perfect for washing away dirt. Kawada Feather produces its beautiful down with the careful use of the benefits of the environment, advanced technology, and human skill and effort.

Down can be washed at home! "The right way to wash down"

"Washing down has a harmful effect on its quality." This is a common misconception. The truth is that washing down correctly will cleanse it of moisture and oil, and bring back its fluffiness. There is no need to wash down frequently. However, we would like to share with you the correct method for washing down, so that you can get the most out of using it.


Place the down in a mesh laundry bag.

Choose the same setting on your washing machine that you would use for a blanket.

Do not use the spin cycle. Instead, wring the down out by hand and dry it in a shaded area out of direct sunlight. Then, pat it down with both hands, and even out any wrinkles.

Green Down: The down recycling project

The Green Down Recycling Project reuses down, which is a finite resource. This project, in which down products from all manufacturers that are no longer being used are collected, refreshed, and reborn as new products, offers several benefits.

The Main Benefits of Recycling Down

Reduces waste, reuses resources, limits carbon dioxide emissions, provides environmental education

Promotes the employment of persons with disabilities
Commissioning of down product sorting and disassembly processes

Contributes to local economies
Partnership with the Red Feather (Central Community Chest of Japan)

Provides stable supply of down
Increased supply and stabilized prices through recycling
