My beloved pair of Iron Heart DC4001 have been worn for 80 days now, and the different hues of blue are popping trough. The Iron Heart denim has a surprising amount of 'depth', considering its weight and other characteristics. Check out some detail shots of the jeans. Some full front- and back pictures will be taken on the next update! Now that the weather is starting to go into the 20's again it'll be a little harder to wear 21oz denim, but I just have to be brave.
