The Iron Heart IH-777-S-SLB 16oz Slubby 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.

A first for Iron Heart, a slubby denim. This deep indigo selvedge denim has a really uneven hand on both the face and the reverse (think off the scale loom-chatter), but at the same time it is incredibly soft and comfortable to wear.

Our Fabric Notes

The 16oz slubby denim features a more irregular texture, giving the fabric a distinct surface character. While still structured, it softens with wear and develops noticeable visual texture over time.

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. Suited for those who appreciate visible fabric character and a more textured fading profile.
