Iron Heart produces some of the nicest flannel shirts around, so it was only natural that Self Edge decided to hit up the denim brand when the store wanted to have their own flannel produced. The pattern, color, hand-feel, weight, and brush level was all laid out by Self Edge. Extremely soft, a versatile dark color, and a warm but breathable fabric round out this material that Iron Heart turned into their first non-snap button shirt. The Self Edge x Iron Heart Dark Rider Flannel is available now via the Self Edge online store in limited quantity.
