ABOUT RIVER

Clothes that don’t
try to look branded.

River is made by a couple who run the select shop “rasiku” in Ninomiya, Kanagawa. Without obvious details or brand signatures, they make timeless clothes in factories in Japan.

River keeps making the same patterns in different fabrics, from sweatshirt fleece to light cotton cashmere. This time, the fabric is a cotton-wool sekketsu.

WHAT IS SEKKETSU
