ONI Denim Men's 13oz Japanese Blue Chambray Jacket - Modern Work Chore Coat Style, ONI-03501-SHVCH One-Wash

ONI Denim

This men's casual chambray jacket is made in Japan by ONI Denim, a brand renowned for its distinctive approach to fabric development and signature craftsmanship. This model offers a modern reinterpretation of the classic work coat, blending elements of the chore coat, engineer jacket, and coverall jacket, and reimagined in a richly textured, durable 13-ounce blue chambray fabric. Expertly constructed with ONI Denim's meticulous attention to detail, the jacket retains a traditional workwear character while incorporating the brand's unique production techniques into a modern silhouette. Its timeless design captures the spirit and aesthetic of vintage American workwear, while blending seamlessly with everyday casual fashion - bridging vintage character with contemporary style. This jacket is made from a 13-ounce blue chambray woven with 100% cotton. The fabric has a richly textured surface with visible slubs, a heathered appearance, and a natural melange effect that gives depth and character. Subtle wrinkling runs throughout the cloth, enhancing its casual look. For added comfort and ease of wear, the garment has been pre-washed (one-wash) to reduce shrinkage and deliver a broken-in feel from the start. The chambray fabric also provides a naturally laid-back feel along with a relaxed, casual character. With its unlined construction, the jacket is versatile for year-round use and especially well-suited for spring and fall wear. The jacket features a front button closure with five metal buttons, each engraved with the Oni Denim logo for an authentic touch. It is designed with set-in sleeves and a regular collar without a collar band, giving it a clean and refined look. The sleeve cuffs are finished with a simple single-needle stitch, without slits or fasteners, for a straightforward and durable construction. The back is cut from single panels to create a clean, seamless appearance. For storage, the jacket includes multiple pockets: an exterior open-top patch pocket on the left chest, two exterior open-top patch pockets at the lower front, and an open-top interior pocket on the right chest. This item is offered in Japanese (Asian) sizing, which typically runs slightly smaller than standard U.S. and European sizes. For reference, a tagged Japan size 38 generally corresponds to a U.S./EU size S to M (approximately 36-38 in garment sizing). Unlike the relaxed fit of classic workwear, this jacket is designed with a modern fit that is neither overly slim nor excessively loose, offering a well-balanced appearance. This item is a brand-new, original creation from ONI Denim, blending classic styling with ONI Denim's unique chambray fabric, modern reinterpretation, and exceptional craftsmanship.
