The Production Of Iron Heart Jeans

The Iron Heart jeans are produced with the highest standards possible. The key of their jeans are heavyweight fabrics that are woven in Japan. In the video of how they produce denim, they will give an insight into the entire process at the Kuroki denim mill in Okayama.

You will learn how raw cotton yarns will transform into to the final weaving process. And all the steps in between such as spinning, rope-dying, rolling, weaving, and sanforization. The brand shows how amazed, but also how complex it is to create their premium-made selvedge fabrics.

How The Iron Heart Brand Started

The Iron Heart denim brand was started back in 2002 by Shinichi Haraki after working for 20 years in the industry. Shinichi Haraki started first as a pattern maker for the Japanese denim brand Edwin jeans. Later he worked as a designer and producer for the brand, ending in the end as the director of the denim company.

With all his experiences he decided to combine his passion for motorcycles and denim, and so Iron Heart was born. To combine both, he decided to make heavy-weight pairs of jeans that can be used perfectly while riding the motorcycle. The jeans are designed to be durable, like their 25oz XHS (extra heavy selvedge) denim jeans.

In 2005, Shinichi Haraki decided to partner with Giles Padmore to manage international sales, marketing, and distribution. Together they worked on a very solid and impressive distribution network of retailers.
