The Iron Heart IH-666S-142 indigo in 14oz Japanese selvedge denim is available at Rugged Gentlemen Shoppe with fast local shipping and easy returns. Iron Heart releases limited quantities of each model, and availability can vary by retailer. Current stock is shown above.
The 666 cut, our "Devil's Fit" slim straight jean with a low/medium rise in our 14oz denim which is made with a double twisted weft yarn (the same construction technique as our 21oz selvedge denim).
Our Fabric Notes
This 14oz denim offers a lighter, more manageable weight compared to Iron Heart’s heavier fabrics. It provides structure without an extended break-in period and is comfortable for year-round wear.
Our Fit Notes
The 666 is one of Iron Heart’s more streamlined straight cuts, with a lower rise and a slimmer fit through the thigh and knee compared to classic models. It offers a clean, contemporary profile while still retaining a straight-leg look rather than a true taper.
Who This Is For
Well-suited for those who prefer a slimmer silhouette and are comfortable with a closer fit through the leg.
