The IHJ-49 Modified Type III Jacket in Brown Roughout is an improved, old-school classic produced in a Japanese Split Steer Leather and is made by Four Speed Japan exclusively for Iron Heart as a robust riding piece appropriate as casual outerwear with a new vintage appeal. Taken from the classic Type III Trucker Jacket debuted by Levi's in 1967, this pattern features a modified body that's been lengthened beyond the belt line for a more modern style. This Steer leather is a durable hide split for garment construction, flipped on the flesh side and brushed for a textured appearance that will matte and patina through heavy wear. This specialized Modified Type III with an outerwear fit is fully lined with a military grade cotton twill and adapted with two internal snapped "gun pockets" for secure retention. This dutiful and durable roughout leather Trucker has been refined and crafted with the signature Type III features of slash front pockets, flap front welted chest pockets, and copper buttons for the front placket, cuffs, and back hem tabs. Built for the biker and over-engineered to start, this Brown Split Steer Roughout Modified Type III will deliver a lifetime of durability in an unmistakable design. The 49-J strikes the balance between climate and culture-appropriate, making it a year-round go-to for a look that's ready for a life on the road.
