Crafted on vintage shuttle looms using traditional skein-dyed black yarns, these 15oz Graph Zero jeans combine early 20th-century workwear heritage with rare Japanese textile craftsmanship. The low-tension weave creates a rugged, uneven texture with rich depth and character, while the grey weft and hand-dyed warp promise distinctive, high-contrast fading unique to black denim. Finished in a wide, straight vintage silhouette with cinch back, suspender buttons, and belt loops, they deliver an authentic 1920s–30s aesthetic with modern everyday wearability.

Fit Notes: Graph Zero jeans generally fit true to size. However, this model runs slightly small, so we recommend sizing up one size. As always, we suggest consulting the size chart to ensure the best fit. Although the denim is unsanforized, it has been one-washed, so no further shrinkage is expected. Due to the low-tension weave typical of Graph Zero fabrics, the waist will stretch with wear—expect approximately 1 inch of stretch over time.

Pascual is 185 cm (6'1") tall and weighs 65 kg (143 lbs), and wears a size 29 in these jeans. He typically wears a size 29 in American brands and a size 29 or 30 in Japanese brands.

The Graph Zero 15oz “Skein Dyeing Denim” Heritage Jeans are a rare reinterpretation of early 20th-century workwear, combining pre-war construction details with an exceptionally characterful black denim fabric that is almost impossible to find today.

Woven in Japan on vintage low-tension shuttle looms, the 15oz selvedge denim is made using traditional skein dyeing (kase dyeing) — a labor-intensive method where the warp yarns are dyed in rope bundles before weaving. Unlike modern industrial dyeing, this process creates natural irregularities in tone and saturation, resulting in a deep, textured black with subtle highs and lows throughout the fabric. Paired with grey weft yarns and uneven slub threads, the denim develops a dry handfeel and a rugged surface full of depth and movement.

The result is a black denim that behaves very differently from standard black jeans. Instead of staying flat and lifeless, the fabric fades gradually and unevenly, revealing rich contrasts and grainy textures that echo vintage indigo denim while retaining its distinctive charcoal-black character.

The silhouette draws directly from 1920s–30s American workwear jeans, featuring a wide, straight leg with a high rise and a full, structured shape. Functional heritage details like a cinch back, suspender buttons, and belt loops give you both authenticity and everyday versatility — a rare combination, especially in black denim. It’s a timeless cut that pairs naturally with boots, jackets, and classic workwear styling.

Finished with Graph Zero’s meticulous craftsmanship — including iron buttons, red tab, tanned leather patch, and vintage-inspired pocket lining — these jeans embody the brand’s dedication to traditional methods, unique textiles, and garments built to age beautifully.
