The Iron Heart Split Steer Modified Type III Jacket in black is built from split steer roughout leather sourced from a small tanning factory in Himeji, the tanning capital of Japan, and made to Shinichi Haraki's design by FourSpeed Leathers, one of Japan's most respected leather specialists. The roughout construction exposes the inner surface of the hide, giving it a soft, velvety nap that develops subtle shading and wear patterns in high-contact areas over time. At 1.4mm, it carries a substantial feel that softens with wear. The Type III silhouette runs slightly longer than the original Levi's version, with flap-down chest pockets, handwarmer pockets, two internal snap-fastened gun pockets, dual hem cinches, and a 100% cotton twill lining. Iron Heart branded tack button fastenings and chainstitch construction throughout.
