Oni is a mysterious label led by a true denim enthusiast who has dedicated over 60 years of his life to the craft. Constantly striving for perfection, Oishi-san focuses solely on production and continuous experimentation. This is why the brand has no official website or Instagram presence, and why it is only available in a limited number of stores worldwide, exclusively at Flâneurs in France.
The 03502 Olive Denim Coverall Jacket from ONI Denim perfectly showcases the brand’s raw and artisanal expertise. Inspired by early 20th-century workwear jackets, this coverall combines a simple and durable construction with a highly characterful denim fabric.
The 18oz denim, woven at low tension on traditional looms, stands out for its extremely irregular and lively texture—an iconic signature of ONI. Its Olive Drab sulfur dye gives it a unique aesthetic, distinct from classic indigo denim. Unlike indigo fabrics, the color evolves more subtly over time, developing a gradual, nuanced patina rather than high-contrast fades. Offered in a one wash version, the fabric is already stabilized and ready to wear, while still retaining the initial stiffness typical of heavyweight denim.
Designed as a functional and durable piece, the straight workwear fit allows for versatile styling, whether worn as a jacket or a layering piece. Finishing details include custom metal buttons, one outer chest pocket paired with an inner pocket, and two large patch pockets. Designed and made in Japan, the 03502-18oz Olive is aimed at denim enthusiasts seeking a textured, distinctive alternative to classic indigo jackets, with a more subtle and refined aesthetic.
