This material was originally created not for apparel, but for things like gi. It’s sturdy but soft and gives a rounded silhouette. It can also be said to be the easiest-to-understand sashiko material among the brand’s many sashiko series. Ozone processing, which does not use harmful chemicals or large amounts of water, bleaches the original color to white, and it is also treated with Teflon to make it easier to remove dirt that accumulates when worn.
