The Iron Heart IH-666S-142 jean is proof that the devil's in the details. Nicknamed the "Devil's Fit", this jean features Iron Heart's proprietary 14oz denim in a modern slim straight cut. It's constructed in the exact same way as their legendary 21oz fabric in that it features a double twisted weft yarn. The 14oz fabric makes this a great option for guys wanting the Iron Heart quality and craftsmanship, but prefer a lighter denim and more modern fit.
