Woven in Ibara, Okayama—one of Japan’s most renowned denim production regions—this 5oz selvedge chambray embodies true craftsmanship.
Using vintage shuttle looms from the early Showa era, the fabric is slowly woven to create a unique texture with natural irregularities and a soft, airy feel.

Both warp and weft yarns are made from slub yarn, allowing the indigo to fade beautifully over time.
More than just a chambray shirt, it is designed to evolve—developing character with every wear.

The embroidery on the chest and back reflects BIG JOHN’s craftsmanship and identity,
adding a distinct presence to this rugged workwear piece.

■ Construction & Details
Built with classic triple-stitched seams, ensuring durability for long-term wear.
Natural shell buttons add a refined touch, balancing ruggedness with subtle elegance.

Selvedge detailing is incorporated into the side seams—
a hidden element that reveals itself over time, reflecting the depth of craftsmanship.

The lightweight 5oz fabric makes it suitable for year-round wear,
whether worn alone or layered.
