All sizes below are Japanese (JP) sizes, roughly one size smaller than US/EU sizing. If you usually wear a size M, we recommend a size L in this item.

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.

Reversible shirt type. Suitable for any occasion and season
空気をまとうから、たった5mmでダウンの暖かさ

軽さの秘密はスペシャルな木の実「カポック」
カポックのワタはコットンの1/8 の軽さ、動物の毛皮や羽毛を使うことも、木を伐採する必要もないスペシャルな素材です。

軽量なのに、ダウンと同じ暖かさを実現
カポックは特殊な構造によって、湿気を吸い、熱を放出する「吸湿発熱」という機能があります。その機能はダウンに匹敵するため、木に実るダウンとも呼ばれています。

最新の加工技術で実現したサステナブルな「エシカルダウンカポック」
カポックは木の実なので木を伐採することも、動物の羽毛をいただくこともありません。
しかし、その繊維は非常に短く、糸にすることが難しいことから、商品化はこれまで難航していました。長年かけて大手企業と共同開発したシートを使用しています。
