The 634 cut is Iron Heart's classic straight leg jean. This iteration is crafted from their 14oz Japanese selvedge denim, made in a similar manner to their 21oz selvedge denim, utilizing a double twisted weft yarn. The 634 fit features a medium rise, and a straight leg shape with an almost imperceptible taper from the knee to the hem.
We find that Iron Heart jeans will stretch an inch in the waist after a few weeks of wear, with other dimensions stretching in proportion to the waist.
