Garment Measurements | Virtual Size Chart


The Iron Heart IHJ-86-BLK Modified Type III Jacket is an armor-like statement piece produced from a 14 oz. medium weight, sanforized, and once washed right hand twill Selvedge Denim from Kojima, Japan. Taken from the classic Type III Trucker Jacket, this pattern features a modified body that's been lengthened beyond the belt line for modern styled grit. A newer fabric within the Iron Heart collection, this 100% cotton denim is woven via vintage shuttle looming using their signature dual twisted weft yarn method to add structure and a slub texture that softens to the body for a remarkable "least heavy" 14 oz. weight fabric in a medium tension weave that has a natural drape and retains its form through years of wear with unmatched durability and performance. Featuring a black sulfur rope dyed warp and black sulfur dip dyed weft over heavy white core yarn, the result is a highly saturated black denim that will fade to high contrast shades of grey. Created to be both a layering or outerwear piece, the Trucker features slash front pockets, a buttoned front placket with interior selvedge line reveal, welted chest pockets with buttoned flaps, internal felled seams, and chainstitched construction throughout. This 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 tests the limits of what actually can be artfully woven and sewn, delivering a lifetime of durability in an unmistakable design.
