Iron Heart 21oz Selvedge Denim Slim Cut Jeans IH-555S-SB - Superblack Non-Fade

About this product

The Iron Heart IH-555S-SB Superblack Non-Fade in 21oz 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 slim cut, medium/high rise jeans, made from 21oz 'Superblack' selvedge denim. If a stealth look is your thing, this is the denim for you. Both the warp and weft yarns are reactive dyed – far more colourfast than our sulphur-dyed fabrics – designed to retain their deep black hue through wear and washing. Utilising a double-twisted weft yarn and lower tension weave, our 21oz denim fabrics are heavy and tough, yet soft and breathable – 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 555 is a slim straight cut with a relatively low to mid rise and a clean line through the leg. It fits closer through the thigh than Iron Heart’s classic straight cuts without feeling overly tapered. This is a good option if you prefer a sharper silhouette while still keeping a straight-leg profile.

Who This Is For

This cut suits those who want a modern, streamlined fit without going fully slim or tapered. Best for experienced denim wearers or those specifically seeking the heavyweight Iron Heart experience.
