The ONI 02527P-DIZR Dark Indigo Secret Denim Type III Jacket translates the full intensity of ONI’s legendary Secret Denim into a timeless trucker silhouette built for extreme texture, everyday functionality, and dramatic fade evolution. Featuring a dark indigo rope-dyed warp paired with a light beige weft, this version is engineered for fast, high-contrast fading with explosive visual depth—perfectly matched to its jean counterparts.

Originally introduced in 2012, ONI’s Secret Denim has become one of the most iconic and sought-after fabrics in modern raw denim, celebrated for its wild slubbiness, hairy surface, deep texture, and unexpected softness despite its extreme 20oz weight. This Dark Indigo variation preserves all of that chaotic character while feeling slightly rougher and more rigid at first, allowing the jacket to evolve with even stronger visual impact over time.

The fabric is produced exclusively by Oishi-san, the master craftsman behind ONI’s most extreme textiles. Using three different types of cotton spun into extra-thick yarns, the denim is woven at ultra-low tension on vintage shuttle looms. The result is a 20oz unsanforized selvedge denim that is deeply uneven, heavily knotted, aggressively slubby, and richly textured—yet capable of molding comfortably to the wearer with use.

The dark indigo warp combined with the light beige weft accelerates contrast, producing electric blues, sharp vertical streaking, and intense high-definition fades across the jacket as it breaks in. This is a piece designed not just to be worn, but to be visually transformed through years of daily use.

Construction is executed with ONI’s uncompromising attention to durability and detail, including custom ONI copper donut buttons, premium pocket bags, and a custom vegetable-tanned cowhide leather patch, all built to withstand decades of hard wear. The classic Type III trucker design is enhanced with functional handwarmer pockets placed at the waist, adding modern comfort without sacrificing the traditional look. The jacket is also finished with interior pockets, offering practical storage for everyday essentials.

The jacket features a balanced, modern fit that allows for comfortable layering while maintaining a clean, structured silhouette. Whether worn as a daily outer layer or as part of a full Secret Denim setup, this piece delivers texture, contrast, functionality, and long-term evolution in its purest ONI form.

Fit Notes: Despite being a Japanese-made jacket, like most ONI garments, the sizing of this Type II leans more Western than traditionally Japanese. If you typically wear a size M in American jackets, you’ll likely find a good fit with a size 40 (M) in this model. However, as always, we recommend checking our size chart to ensure the best fit. The jacket has been once-washed, so no further shrinkage is expected.
