This pair of Iron Heart 634SR's have been worn for 8 months. They got a soak when they were new, so the extremely heavy 23oz denim wouldn't destroy the threads holding the jeans together. After 8 months, they received a hand wash.
The Iron Heart 634SR was created to celebrate Iron Hearts 5 year anniversary. As you can see in these pics, they fade in a very typical way, different than the regular 21oz denim.
