Garment details

Need-to-know info pulled from the retailer’s description, sizing notes, and care callouts.

This special release from Pure Blue Japan reimagines the brand’s Extra Slub Series with a unique combination of sulfur black and kakishibu dye treatments. Kakishibu, a traditional Japanese dyeing technique, uses fermented persimmon tannins aged for at least two years to produce a rich amber hue that fades and transforms similar to indigo. The denim’s deep black surface comes from a sulfur dye process, in which sulfur compounds bond to the yarn’s outer layer. The result is a fabric that evolves beautifully with wear, highlighting the depth of both dyes and the dramatic texture of the ultra-slubby yarns. As with other styles in PBJ’s catalog, this denim is woven on vintage shuttle looms using a slow, deliberate weaving process to create the brand’s signature texture. Finished with custom hardware, a deerskin leather patch, and Pure Blue Japan’s iconic indigofera leaf embroidery.
