What is Iron Heart denim

Iron Heart is a Japanese brand founded in 2003 by Shinichi Haraki, a former designer at Edwin. The brand specializes in ultra-heavyweight selvedge denim, often ranging from 14oz to 25oz, designed to withstand the rigors of motorcycle riding. Their garments are crafted with meticulous attention to detail, combining traditional Japanese techniques with durable materials

How does Iron Heart's denim compare to other Japanese brands

While brands like Kapital and Visvim focus on avant-garde designs and cultural narratives, Iron Heart emphasizes durability and functionality. Their denim is known for its weight and resilience, appealing to those seeking robust, long-lasting garments

How does Iron Heart's sizing compare to other brands

Iron Heart's sizing can differ from other brands, often running slightly smaller. It's recommended to consult their detailed sizing charts and consider sizing up if you're between sizes

What’s the best way to care for heavy denim

Wash infrequently, air dry, and spot clean as needed. For example, Iron Heart recommends turning jeans inside out and washing in cold water to preserve indigo and fabric strength

Can I wear heavyweight jeans in warmer weather

It depends on your tolerance, but many enthusiasts wear 14oz–17oz denim year-round. Iron Heart offers “lighter” heavyweights like 14oz and 17oz for summer wear, with breathable weaves and soft feel after break-in

What’s the difference between sanforized and unsanforized denim

Sanforized denim is pre-shrunk, while unsanforized denim can shrink significantly after the first wash. Iron Heart typically uses sanforized denim, offering consistent sizing and minimal shrinkage, which makes fit selection easier

What does 'one wash' denim mean

“One wash” refers to denim that’s been lightly rinsed to remove shrinkage. Iron Heart offers both raw and one-wash options, depending on whether you want to shrink your jeans yourself or get closer to final fit from the start

Product Description

This heavyweight 21oz "Superblack" selvedge denim jacket combines Iron Heart's iconic Modified Type III cut with a unique, high-contrast fading process. The combination of a sulphur-dyed warp, which gradually fades to grey, and a reactive-dyed weft, which retains its deep black tone, creates the signature "Superblack" look, ensuring this jacket will develop distinct fade marks with wear.

Designed with functionality in mind, the jacket features hand-warmer pockets that double as internal storage and chest flap pockets with tack button fastenings. The construction is reinforced with tonal stitching, poly/cotton stitching at the seams, and yellow bobbin thread for long-lasting durability. The fit of this jacket is a unique blend of classic and contemporary styles, offering a slightly fuller body and arm fit, ideal for those who appreciate a vintage-inspired aesthetic.

What We Think

When you think Denim Jacket, you probably have the Type III in mind. Established in the 1960s by Levis, it became the standard. Iron Heart have nailed it in their iconic heavyweight 21oz denim and a black colour that fades as you wear it. For those wanting to wear double denim but don't want it to match, the black colour looks perfect with Indigo. Also perfect with chinos, work pants and anything hard wearing.
