Iron Heart
Ultra-heavy 21oz+ denim, shuttle-woven, Aspero cotton, Japan since 2003
Philosophy
Born from motorcycle culture and 20 years of experience at Edwin, Iron Heart produces the heaviest denim on the market. Aspero cotton dyed in Niigata, vintage shuttle loom weaving, indestructible construction. For those who consider jeans equipment, not clothing.
History
Shinichi Haraki spends twenty years at Edwin, entering as pattern maker, rising to production director. In 2003, he founds Iron Heart under The Works Inc. Inspiration: the Japanese-American motorcycle community. Bikers need jeans that withstand the road. Standard 12-14oz won't do. Haraki starts at 21oz.
Hand-picked Aspero long-staple cotton, dyed in Niigata with repeated natural indigo baths, woven on vintage shuttle looms. Fabric so dense it stands on its own. Takes months to break in. Among enthusiasts, Iron Heart reviews are events - one-year wear reports with religious reverence. The Ultra Heavy flannels are equally legendary. Distribution through ironheart.co.uk (Giles Padmore), Self Edge USA. An IH-634S costs about 350 euros. It's the last pair of jeans you buy.
