It has been 20 years since the inception of Iron Heart, and to celebrate this milestone we are taking things back to where it all started, with a limited run of Haraki san’s first Iron Heart jean design, the 634 - our classic straight cut. A little-known fact is that Haraki san came up with the name Iron Heart for his new brand whilst standing in the bathroom after a few beers with friends, discussing his vision for the future.
This 20th anniversary edition features many of the same details found on our standard model but with several special features. They are, of course, constructed from our signature 21oz selvedge indigo denim, but the arcuates on the rear pockets of each pair of jeans have been individually chain stitch embroidered with gold thread, a very time-consuming process carried out by the very talented Hayakawa san. We have also switched out the cowhide back patch for a black cordovan horsehide leather version, which has been hand embossed with a custom 20th-anniversary design by Hirao san of Wedge Leathers who produce Iron Heart’s leather goods. The left front pocket bag has been two-colour screen-printed with a special anniversary design. And if this was not enough, the lot number and size has been stamped onto the patch by Haraki san himself.
No tax
