XXXX-EXTRA ONE WASH JACKET represents BIG JOHN's pursuit of Japanese denim craftsmanship at its highest level.
Created with the ambition to produce jeans that showcase the finest skills of Japanese artisans, the XXXX-EXTRA collection brings together carefully selected cotton, original yarn development, traditional indigo dyeing, vintage weaving techniques, and meticulous Japanese manufacturing.
This denim jacket is made from 15.8 oz Japanese selvedge denim, rope-dyed 16 times with 100% natural indigo. Its substantial weight, distinctive texture, and deep indigo color reflect the craftsmanship behind the XXXX-EXTRA collection.
The RINSE / ONE WASH finish gently softens the fabric while preserving the rugged character of heavyweight denim. The result is a jacket that feels more comfortable from the first wear and continues to develop its own personality over time.
Inspired by classic denim workwear, the jacket features an authentic two-pocket design, original BIG JOHN hardware, and carefully selected heritage details.
Exceptional materials, traditional Japanese craftsmanship, and the evolving beauty of natural indigo. A denim jacket designed to be worn, appreciated, and aged for years to come.
This jacket is washed once after production, giving the substantial 15.8 oz denim a naturally softened feel while maintaining its distinctive texture and structure.
The washing process helps reduce the major initial shrinkage associated with untreated raw denim, making the jacket easier to wear and size from the beginning.
With continued wear and washing, the natural indigo gradually fades, creating individual creases, abrasion patterns, and rich tonal contrasts unique to the wearer.

An additional 5% of OCS-certified recycled organic cotton is incorporated into the blend.
Each cotton variety contributes its own characteristics, creating a distinctive balance of texture, strength, and natural character.
The natural variations in yarn thickness create a dimensional denim surface with distinctive irregularity, depth, and a vintage-inspired appearance.
This exceptional process, a first for Sakamoto Denim, produces a deep, rich indigo color while preserving the characteristic white core of rope-dyed yarn.
As the surface indigo gradually wears away, the lighter inner fibers become visible, creating distinctive fading, highlights, and contrasts that evolve with continued wear.
By weaving slowly without placing excessive tension on the yarn, the fabric develops a naturally textured surface with substantial body and a surprisingly approachable feel for its 15.8 oz weight.
The selvedge features an original indigo edge made using the same natural indigo yarn as the fabric itself, reflecting BIG JOHN's attention to even the smallest details.
Its straightforward silhouette allows the character of the heavyweight selvedge denim to take center stage.
Original BIG JOHN metal hardware, a vegetable-tanned leather patch, and a rayon brand label complete the authentic heritage-inspired design.
