The Iron Heart IH-888S-SLB in 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 888 has a higher rise with more room in the top block, tapering gradually from the knee to the hem. This creates a balanced silhouette that feels comfortable in the seat and thigh while still offering a cleaner leg opening.
Who This Is For
A good choice for those who want comfort in the top block with a more refined, tapered shape below the knee. Suited for those who appreciate visible fabric character and a more textured fading profile.
