Iron Heart is one of the primary staples of heavyweight denim for good reason. Honestly, this pair is as tough as nails.
This week’s Fade Friday takes a look into Iron Heart 634S-RAW, courtesy of SuFu’s ThinFinn and a branch from the all-too-famous IH-634S. These were limited in rotation and have a couple of different features to separate them from the IH-634S. The jeans made from a 21 Oz. denim that shrinks to 23 Oz. due to the fact that it is unsanforized, and the pockets feature an interesting half-lining.
This pair has extraordinary fades, starting with the large deep honeycombs and even fade around the knees and thighs. The ‘combs have a really prominent fade that can only come from dealing with some of the most heavyweight denim.
