About this product

The Iron Heart IH-777S-21od in 21oz indigo overdyed black Japanese selvedge denim is available at Rugged Gentlemen Shoppe with fast local shipping and easy returns. Iron Heart produces limited runs of each model, and popular sizes are often difficult to find. If your size is available, you can secure it here while stock lasts.

Our low rise, slim tapered cut jeans, constructed from 21oz overdyed indigo selvedge denim. To create this darkened variation, we take a pair of standard IH-777S-21 jeans and steep the entire garment in black dye using a direct dyeing process. This stains the indigo denim and stitching, with the added bonus of removing all shrinkage from the fabric. A unique middle ground between our traditional indigo and black denims, over time the fabric will gradually fade with blue-tinged hues in high-wear areas.

Please note that previous versions of these jeans were overdyed using sulphur dye. Due to the environmental impact of sulphur dyes, we have decided to switch to a direct dyeing process when overdyeing our heavyweight denims. The only noticeable difference is that this new process does not oxidise the brass hardware as previously. You can still expect these jeans to age and fade similarly to older models.

Our Fabric Notes

Iron Heart’s 21oz signature denim is known for its dense weave and substantial weight. It feels rigid when new and requires a break-in period, softening gradually with wear. Over time, it develops strong, high-contrast fading.

Our Fit Notes

The 777 features a slim fit through the top block with a noticeable taper from the knee down. It offers a more modern shape compared to Iron Heart’s traditional straight cuts, while still maintaining a structured, heritage feel.

Who This Is For

Ideal for those who want a contemporary, tapered fit without moving into ultra-slim territory. Best for experienced denim wearers or those specifically seeking the heavyweight Iron Heart experience.
