Graph Zero 13oz "Natural Dyeing Kakishibu" Regular Straight Jeans

From Kojima, Kurashiki — Japan's denim heartland — Graph Zero presents a remarkable expression of tradition and innovation: selvedge jeans dyed with kakishibu, a natural tannin dye extracted from unripe persimmons. Crafted from 13oz organic cotton, the denim is woven on vintage shuttle looms to achieve a rich, textured fabric with distinctive uneven character and a hand-woven feel. The kakishibu dyeing process uses the traditional kase-zome (skein dyeing) method, in which each individual yarn is dyed by hand. This produces subtle irregularities and a complex, earthy tone that deepens with age. Unlike indigo — which fades over time — kakishibu naturally darkens through exposure to sunlight, developing a patina personal to the wearer and unlike anything in a conventional indigo pair. The warp threads are dyed with persimmon tannin, while the weft remains undyed. Both are nep yarns, producing a slubby, vintage-inspired surface that captures the essence of early workwear with a modern edge. Inspired by 1940s wartime five-pocket jeans, the regular straight cut with a high rise has been reinterpreted with Graph Zero's signature attention to detail: hidden rivets, chainstitched hems and waistband, cotton sewing threads that age beautifully, a brown selvedge ID, a selvedge coin pocket, a red tab on the back pocket, custom Japanese pocket lining, and a debossed cowhide leather patch. Fit Notes: Graph Zero jeans fit true to size — the tagged size closely matches the actual waist measurement. Compared to most global American brands, we recommend taking your usual size — or sizing up one from your usual size for a slightly more relaxed fit. The denim is unsanforized but has been one-washed, so no further shrinkage is expected. Due to the low-tension weave typical of Graph Zero fabrics, the waistband will stretch approximately 1 inch with regular wear, allowing the fit to settle comfortably over time. As always, we strongly recommend checking our size chart and comparing it to your best-fitting pair to find the perfect size.
