Where Japanese denim began—redefined in a wider silhouette.
A legacy rooted in the 1960s.
In the early days of Japanese denim, BIG JOHN pioneered the culture by crafting jeans from imported American fabrics.
The SL VINTAGE Series revives that original texture and spirit—reconstructing it with modern precision while preserving its raw authenticity.
What if the first Japanese jeans evolved for today’s style?
This model answers with a loose straight silhouette—a classic wide fit that reflects vintage workwear while adapting seamlessly to modern wardrobes.
■ Fabric — 12oz Selvedge Denim (TOYODA Shuttle Loom)
Woven on the historic TOYODA GL-3 shuttle loom, this 12oz selvedge denim offers a rare balance of structure and comfort.
Made from a blend of American and Australian cotton (28–29mm fiber length), and spun into slub yarns (warp #7 / weft #10), the fabric develops a naturally uneven, vintage texture.
Dyed with 100% pure indigo using rope dyeing, it delivers a deep, rich tone that fades beautifully—aging uniquely with every wear.
■ Details — Faithful to vintage construction
• Button fly construction for classic authenticity
• Sewn with #8 thick cotton thread, true to 1960s specifications
• Specially treated paper patch designed to withstand aging and wear
• Original BIG JOHN hardware: buttons, rivets, labels, and trims
■ Fit — Loose straight / classic wide silhouette
Designed with a relaxed, wide-leg profile, offering both comfort and presence.
The moderate rise ensures a natural fit, while the silhouette pairs effortlessly with sneakers, boots, or heritage styling.
Model is 175cm / 65kg wearing size 32.
