What to know about Iron Heart
Weight is the whole premise
Iron Heart built its name on 21oz selvedge denim and Ultra Heavy Flannel shirting, fabrics far thicker than the 12–14oz standard most denim brands use.
Designed around motorcycles first
The label started for Japan's riding community, so fits like the IH-634 jean are cut for movement on a bike rather than for a slim silhouette.
Fabric developed in-house, sold from UK
Founder Shinichi Haraki, formerly a patternmaker at Edwin, runs production from fabric development through to garment; global sales go through a UK-owned arm.

Brand facts
Iron Heart is a Japanese heavyweight denim and workwear label founded in 2003 by Shinichi Haraki under his company Works Inc., after two decades at Edwin as patternmaker and designer. Built originally for Japan's motorcycling community, the brand is defined by 21oz selvedge denim, the IH-634 jean, and Ultra Heavy Flannel shirting, with fits engineered for riding comfort. Its slogan, "over-engineered is our starting point," frames vertical production from fabric development to garment. Global sales run through Iron Heart International, a UK company owned by Alex Padmore, plus Japanese stores in Hachioji, Kojima, Nagoya and Osaka.
