XXXX-EXTRA is BIG JOHN’s flagship denim project—an ambitious expression of excellence, driven by one mission: to create jeans Japan can proudly share with the world. This collection gathers the finest techniques and artisanship from across the nation.
The XX003 EXTRA WIDE STRAIGHT features a slightly roomier straight-leg silhouette for a relaxed yet refined look. Crafted from 12.0oz natural indigo-dyed selvedge denim, it offers a lighter, more comfortable wear with unmistakable presence.
Every detail—from silhouette to stitching to construction—has been obsessively refined. This is a new standard in denim: a pair designed not just for denim purists, but for anyone who seeks the authenticity of true craftsmanship.
