Garment Measurements | Virtual Size Chart


The Iron Heart x Division Road IHDR-502IB Serviceman in Indigo x Black Selvedge Denim is a new development based on the 888 cut as a Classic Tapered fit with a mid-high rise, roomy seat, moderate thigh, and a modern-meets-vintage tapered leg with a moderate hem for full functionality and style versatility. This exclusive collaboration was designed to infuse military, workwear, and moto club inspirations, materials, and production techniques to create an evolved collectible for our Division Road Army on their journey from the barrack to the battlefield. Being true to the originals with a heritage update, this Serviceman Cargo features the Iron Heart Signature 14 oz. medium weight, sanforized and once-washed right hand twill Japanese Selvedge denim, made with two twisted yarns to add structure to a "least heavy" weight fabric in a medium tension weave, which will become amazingly soft, retain its form, and have unmatched durability through years of wear. Perfect for the gent who lives his history in the present, this proprietary 100% Cotton selvedge denim is woven via vintage shuttle looming, featuring an indigo rope dyed warp and black sulfur dip dyed weft over heavy white core yarn that results in a highly saturated navy that will fade with a high contrast in steely shades of electric blues. Built for the motorcycle community and over-engineered to start, Iron Heart tests the limits of what actually can be artfully woven and sewn. The Serviceman Cargo stays true to this tradition of enhancing moto-ready builds with a beyond military grade disposition, evident from the double layer knee panel and cargo flap pocket reinforcement, brass riveted slash front pockets, welt back pockets, heavy duty canvas pocket bags, and gusseted cargo pockets with a military grade engraved copper snap button closure. Furthering the elevated execution of this modern free rider military cargo pant remake is the use of a reproduction Talon zipper fly, bartack reinforcements, and triple chainstitched flat felled inseam and outseams with heavy gauge chainstitching construction throughout to ensure a lifetime of utility while signifying your cult collector rank.

The 502DR-IB Cargo runs true to Iron Heart sizing, and we suggest going down 0-1 sizes from your Actual Waist Measurement (Body). Made with a sanforized and once washed fabric, most shrinkage is removed. With regular use, one can expect up to 1” of stretch in the waist over the long term. 

Our Method of measuring is different than Iron Heart. We recommend consulting our Sizing Guide and using our Virtual Size Chart to reference our Method when purchasing.
