The Iron Heart IH-777S-21 in 21oz 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 slim tapered cut, low rise jeans, made from 21oz indigo selvedge denim. If there’s one particular fabric most commonly associated with Iron Heart, this would be it. Utilising a double-twisted weft yarn and lower tension weave, our signature 21oz denim fabrics are heavy and tough, while softer and more breathable than other heavyweight denim — creating a pair of jeans that mould to the wearer’s body shape like no other.
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.
