Iron Heart IHSH-337

Iron Heart is a brand that prides itself on creating high-quality clothing that is built to last. Their UHF (Ultra-Heavy Flannel) shirts are no exception, and the production process behind these shirts is a testament to the brand's commitment to quality, here we take a closer look at the Tartan green check western IHSH-337


One of the key ingredients in Iron Heart's UHF shirts is the Peruvian Aspero cotton used to create the fabric. Aspero cotton is a special variety that is known for its long staple length and unique texture. The cotton fibers are hand-picked and undergo a rigorous spinning process to create a dense, heavy fabric that is incredibly soft to the touch.

Iron Heart sources this cotton from a single farm in Peru, ensuring consistency and quality throughout the entire production process. The cotton is then shipped to Japan, where it is woven into the signature UHF fabric using vintage looms. This process creates a fabric that is not only incredibly durable but also has a distinctive texture and drape.

Once the fabric is woven, it is cut and sewn into shirts using traditional Japanese techniques. Iron Heart is known for their attention to detail, and this is evident in the quality of the stitching and finishing on their shirts. Each shirt is made to last, with reinforced seams and durable buttons and snaps that are designed to withstand heavy wear.

One of the standout features of the IHSH-337 UHF shirt is the unique pattern. Iron Heart Boss Haraki San' designs are constantly pushing the boundaries of what is possible with flannel, and this western shirt is a prime example of his creativity. The pattern features a green 'tartan check' that is eye-catching without being too overwhelming.
