So this pair of Iron Heart DC4001's have been worn for almost 2 months. The denim has really softened up, thank god. They are actually pretty comfortable now! Wearing 21oz denim has a downside though: it makes all your 'regular' weight jeans feel like silk pyjamas. The indigo is breaking in a bit as you can see in these pictures. Still, it's only been 2 months and since this pair is competing in a 2 year contest with other heavyweight jeans, you can expect a lot more from this pair in the future.
