Garment Measurements | Virtual Size Chart


The IH-70J Modified Type III Jacket is an improved old school classic produced in a 100% Cotton Japanese 13 wale per inch Corduroy and once-washed to remove shrinkage while also adding a worn in vintage appeal. Taken from the classic Type III Trucker Jacket debuted by Levi's in 1967, this pattern features a modified body that has been lengthened beyond the belt line for modern styled grit. The specialty fabric was developed specifically for this piece to provide softness and texture with insulation and wind blocking qualities. 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. Our Modified Type III strikes the balance between climate and culture appropriate, making it a year-round go-to for a look that packs a punch. Built for the biker and over-engineered to start, this jacket will deliver a lifetime of durability in an unmistakable design.
