Iron Heart
Founded in 2003 by Shinichi Haraki, Iron Heart is the gold standard for heavyweight Japanese denim. Originally designed for bikers, the brand focuses on extreme durability and classic workwear silhouettes. Their legendary 21oz denim—ultra-heavy yet surprisingly soft due to its breathable weave. Everything is Made in Japan, featuring triple-needle stitching and "over-engineered" hardware. Function over fashion. They don't follow trends; they build gear meant to survive a slide on the asphalt or a decade of daily wear.
