Ships from Japan within 3–5 business days; international delivery typically takes 7–14 days.
An eco-conscious jacket made with recycled nylon and kapok down. The outer shell is recycled nylon with a plant-based resin coating on the reverse for water and wind resistance; the lining is anti-static polyester.
It delivers the warmth of a classic down jacket while staying thin — no puffy silhouette, and no feathers to escape. The hood is lined with a soft brushed fabric, and a drawcord at the waist lets you adjust the silhouette. Hand-washable at home, so care is simple too.
This jacket raised over ¥15,000,000 in 3 months on Makuake, Japan's leading crowdfunding platform.

Wash in a laundry net, and use a pressing cloth when ironing. Avoid fabric softener where possible — it can cause loss of shape and seam slippage. Do not soak for long periods or leave the garment wet with water or sweat, as this may cause colour loss or colour transfer. Due to the nature of the material, some filling or fine fibres may work their way to the surface with washing and wear. If any filling pokes out, do not pull it — trim it with scissors.
