HOT ! 14oz Selvedge Denim Straight Cut Jeans IH-634S-142BB - Black/Black

The Iron Heart IH-634S-142BB Black-on-Black in 14oz Japanese selvedge denim is available at Rugged Gentlemen Shoppe with fast local shipping and easy returns. Due to limited production, certain sizes can be hard to find once they sell through. If your size is currently available, it may be worth securing it while stock lasts.

Our traditional straight jean cut in 14oz black selvedge denim. Unlike reactive-dyed \"Superblack\" denim, this fabric is woven with a black sulphur rope-dyed warp yarn and a black sulphur-dipped weft. Finished with tonal stitching, expect these jeans to gradually fade to grey with wear and washing.

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 634 is Iron Heart’s classic straight cut, offering a mid rise and an even fit through the leg. It provides more room than the 555 and 666, making it a reliable reference point for those new to the brand.

Who This Is For

Best for those who prefer a traditional straight-leg fit and a balanced, all-around silhouette.
