Fitting guide

What we Think: The 666 fit (or, "The Devil's Fit") from Iron Heart is a slightly slimmer variation of the popular 634 (straight leg) fit. It, like the 634, comes in Iron Heart's signature 21oz fabric. This indigo jean has been overdyed (dyed a second time) in a black-sulphur dye; with wear and wash it will begin to reveal the indigo character underneath the black dye. The overdying process also guarantees that the jean will shrink marginally, if any, in the wash. What Iron Heart has done with this jean is bring their usual eye for detail and second-to-none construction to a jean silhouette that will please, well, pretty much anyone. 

Wash: "Over dye black" – an indigo jean that has been constructed and then dyed black for a black colour that shows hues of indigo below. 

Fit: A slim-straight leg.

Inseam: 36” inseam.
