Garment Measurements | Virtual Size Chart


The Iron Heart IH-526-ODG Modified Type III Jacket in Olive Drab is an improved old school classic produced in an 100% Cotton 11 oz. heavy duty Whipcord twill that is once-washed to remove shrinkage while also providing flexibility in a robust fabric 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 Whipcord is fashioned after military-grade fabrics made from a hearty cotton in a hard twisted yarn woven into a twill that creates a corded ribbing effect while adding durability. This specialized Modified Type III adds a brown corduroy collar for a tonal accent with a vintage flavor, in addition to a lining in the pockets and cuffs for a finished feel. Created to be both a layering and outerwear piece, the Trucker features slash front pockets, copper buttons for the front placket and flap front welted chest pockets, along with internal felled seams and chainstitched construction throughout. Built for the biker and over-engineered to start, this Olive Drab Whipcord Modified Type III will deliver a lifetime of durability in an unmistakable design. The 526-ODG strikes the balance between climate and culture-appropriate, making it a year-round go-to for a look that is truck stop ready with battlefield bravado.
