Pure Blue Japan 1185 Back Satin Sulfur Yarn-Dye Trousers – Navy / Wide Straight

The Back Satin Sulfur Yarn-Dye Trouser shows another side of Pure Blue Japan. Instead of denim, this model uses a richly textured back satin fabric that combines workwear character with refined everyday wearability. Cut in the brand’s newest Piped Straight fit, it features a high rise, generous room through the top block, and a wide straight leg from waist to hem. The result is relaxed, balanced, and exceptionally comfortable without losing structure.

The fabric is where this pair stands apart. Woven from 100% cotton, the warp yarns are sulfur-dyed navy while the weft is dyed black, creating a deep tonal color with remarkable depth. Irregular yarns introduce subtle horizontal movement across the surface, while the matte finish of back satin gives the trousers a clean yet expressive appearance. Soft from the first wear, the cloth will gradually fade and develop character over time.

Details include a zip fly, slant front pockets, rear welt pockets, herringbone pocket lining, and PBJ’s signature Shoai leaf embroidery. A rare trouser from one of Japan’s most respected mills, built for those who value fabric innovation as much as fit.
