A modern take on a heritage staple, the IHSH-326 is one of Iron Heart’s longest-running work shirt designs—reimagined with rugged snap closures and built from premium Japanese selvedge denim.
Constructed from 12oz sulphur-dyed black selvedge denim, this shirt delivers the brand’s signature balance of durability and refined craftsmanship. The fabric will gradually fade with wear, revealing depth and character unique to each owner. Designed in a classic work shirt silhouette, it features dual chest pockets with a pen holder, reinforced stitching throughout, and Iron Heart’s signature over-engineered construction.
Unlike traditional button-front work shirts, the IHSH-326 uses heavy-duty Permex snaps for ease of wear and added toughness—making it equally suited for everyday use or layering.
