WWII 40's Sumi Coated Linen Coverall
The WWII 40’s Sumi Coated Linen Coverall from orSlow draws direct inspiration from 1940s American workwear, reinterpreted through the brand’s meticulous Japanese craftsmanship.
Cut in a classic coverall silhouette, the jacket features a relaxed, slightly boxy fit true to original wartime garments. The fabric is where this piece truly stands apart — a breathable linen base treated with a traditional sumi-inspired coating, giving the surface a deep, ink-like richness and subtle texture.
The coating enhances both character and depth, allowing the garment to evolve beautifully with wear. Over time, creasing and movement will reveal natural variation, reinforcing the authentic vintage expression that defines orSlow.
Functional detailing, practical pockets, and durable construction ground the design firmly in its utilitarian roots, while the refined fabric treatment elevates it beyond a standard reproduction.
A heritage workwear piece with distinctive surface character.
Made in Japan.
