Iron Heart IH-777S-21mb 21oz Selvedge Denim Slim Tapered Cut - Mad Black

The Iron Heart IH-777S-21mb jean is Iron Heart's Super Slim Tapered cut, but to be honest, it's not as extreme as the name suggests. Relative to the IH-634S this jean is a slimmer cut to be sure, but in all honesty, this jean is just a great modern taper. This version features what Iron Heart calls a little bit of "black magic". While Iron Heart is keeping details of the process a deep dark secret, they did reveal that they used two different black dyes and two different dye methods. The result is a deep, dark black denim that will fade slowly and only begrudgingly reveal its secrets.
