Japan Blue Jeans JBOT1324 Sashiko Coverall Jacket - Black

A modern reinterpretation of the classic workwear coverall jacket, this black sashiko piece blends everyday wearability with a clean, refined silhouette. Based on vintage coverall jackets and reworked with Japan Blue Jeans’ modern sensibility, it features a slightly fitted shape, a slightly shorter length, and four functional front pockets for a practical workwear feel with a more polished finish.

The fabric is an 11oz black sashiko woven for softness and flexibility, making it comfortable for daily wear. The black yarns are sulphur-dyed in the same way as traditional black denim, designed to fade gradually into subtle grey tones over time. Originally used for firefighters’ coats, sashiko is known for its thick, interwoven cotton structure, giving this jacket durability as well as distinctive character. Made in Japan from 100% cotton.
