Surprisingly light. Incredibly warm.

Ultra Light Down Jacket

The secret to this jacket's surprising lightness is the special fabric designed in cooperation with Toray Industries. By double-layering without down packing, we were able to achieve an overwhelming reduction of weight. Because of our use of premium down, the jacket stays thoroughly warm despite how light it is. A pouch is attached for storage, making it easy to pack and carry as well.

Product stories

So light, you’ll forget you’re wearing it.

We worked with Toray to develop a special fabric to create Ultra Light Down with a 2-layer structure that is noticeably more lightweight compared to the traditional 4-layer structure. The key is a fabric woven with fine, high-density nylon yarn approximately one-tenth as thick as a human hair. It’s comfortable, warm, and unlikely to lose feathers.

Airy wear that stays warm.

Fill power is one of the indicators of down quality: a higher count means more air is contained in the down, making it better at retaining heat. Our Ultra Light Down is of high quality, with a fill power of over 750. We also use the golden ratio of 90% down to 10% feathers to maximise warmth.
