Made with Pertex Quantum fabric, it offers a soft touch, lightweight feel, and excellent durability. The jacket is packable and can be stored in the left chest pocket. It is compatible with the ZIP IN ZIP system, allowing it to connect with an outer shell. This is a versatile piece suitable for active wear. Model compatible with ZIP IN ZIP (women's).

It's warm.

The feather shaft may come out of the fabric, but it is compact and easy to use. You won't feel restricted while driving a car even when wearing it.

Light and warm.

This year's model is said to have down filling in the front and back bodice below the shoulder switch, making it light and warm! It can also be compact, which could come in handy while traveling!

PERTEX Quantum

PERTEX Quantum

A series of lightweight high-density materials that are flexible and durable. By suppressing ventilation, down-proof properties are achieved.

CLEANDOWN
2/9

CLEANDOWN

CLEANDOWN uses raw down that has been cleaned and processed by KAWADA FEATHER, a down processing manufacturer located in Meiwa-cho, Mie Prefecture. In a dry climate where down feathers can open easily, soft water from this area is used to thoroughly remove dirt and dust without damaging the down, resulting in clean down. The cleaned down has better loft than before cleaning and improved insulation. Clean down wraps the body more warmly.

GREEN DOWN RECYCLE PROJECT

The GREEN DOWN RECYCLE PROJECT is a project to collect and refine down (feathers), which are a limited resource, and use them as raw materials for new products, including down clothing, under the name 'GREENDOWN'. It helps reduce the carbon dioxide emitted when down is incinerated (approximately 1.8 kg of carbon dioxide is emitted for 1 kg of down) and the carbon dioxide generated when transported from the country of origin to Japan.
