XX604 (001) 12oz Natural Indigo Selvedge Denim – Coveralls, 100% Organic Cotton from Five Continents

BIG JOHN XXXX-EXTRA Coverall Jacket represents the highest level of Japanese craftsmanship — a workwear masterpiece proudly made in Japan.

This long-awaited addition to the “XXXX-EXTRA” series was created with the idea of combining traditional workwear spirit with modern comfort and refined design.

Featuring a clean three-pocket coverall style, this jacket highlights the deep, rich tone of natural indigo. The silhouette has been carefully updated to fit today’s lifestyle while maintaining the authentic vintage appeal.

The 12oz selvedge denim is woven from a unique blend of five types of organic cotton sourced from five continents and spun into Structure Yarn by Taisho Spinning. The yarns are rope-dyed 16 times in 100% natural indigo by Sakamoto Denim, resulting in a deep, pure blue that ages beautifully over time.

Woven on vintage shuttle looms by Shinya Textile, the fabric has a natural uneven texture and a soft hand feel. Every detail — from the iron donut buttons engraved with “BIG JOHN 1940” to the original leather patch and rayon label — has been exclusively designed for the EXTRA line.

This is not just a coverall. It’s a symbol of BIG JOHN’s dedication to authenticity, quality, and timeless Japanese craftsmanship.
