GRAPH ZERO "PERSIMMON TANNIN" 13OZ NATURAL DYEING REGULAR STRAIGHT JEANS

Graph Zero’s 13oz naturally dyed selvedge denim is a deliberate step back to the origins of workwear, where character was earned through process, time, and wear. Woven in Japan on a traditional power loom, this raw denim is left entirely untreated—free from anti-shrink, anti-twist, or singeing processes. The result is a fabric that feels alive, carrying the irregularities and depth that define true vintage denim.

What sets this denim apart begins at the yarn stage. Each strand is hand-dyed in skeins using natural persimmon tannin, known as kakishibu. Unlike modern rope dyeing, skein dyeing allows the dye to penetrate the yarn unevenly, creating rich, organic tones that evolve dramatically with wear. The warp threads are dyed with natural persimmon, while the weft remains undyed, natural cotton—an intentional contrast that enhances depth and aging potential.

To further amplify texture, Graph Zero incorporates nep yarn both vertically and horizontally. This gives the fabric a rugged, almost handwoven feel, with subtle slubs and imperfections throughout. The surface is coarse and expressive at first, but softens beautifully over time. As the denim breaks in, it develops distinctive, high-contrast fades that are unique to skein-dyed fabrics—far removed from the predictable patterns of conventional denim.

The construction draws direct inspiration from authentic 1940s wartime five-pocket jeans. Practical, understated, and built for durability, the design reflects the restrained details of the WW2 era, when material conservation shaped both form and function. Period-correct elements such as hidden rivets, a hidden bar tack, and a button fly reinforce the historical reference, while Graph Zero’s original iron buttons and a tanned leather patch add a refined, brand-specific finish.

Finished with a single wash to remove excess starch while preserving the raw character, these jeans are made to age alongside the wearer—telling a personal story through fades, creases, and wear patterns that can never be replicated.
