Garment Measurements | Virtual Size Chart


The Iron Heart 555S-142 is a solid high rise Super Slim Fit with a roomy seat, moderate thigh, slim leg and narrow hem. This jean features the Iron Heart new signature 14 oz. medium weight, sanforized and once-washed right hand twill Japanese Selvedge denim. This material is made with two twisted yarns to add structure to a "least heavy" weight fabric in a medium tension weave, which will become amazingly soft with a drape that will retain its form through years of wear. A new fabric within the Iron Heart collection, this 100% cotton denim is woven via vintage shuttle looming of the dual yarn method to produce a slight slub on the inside weft that softens to the body and gives this remarkable medium weight denim unmatched durability and performance. Featuring a rope dyed indigo warp and a natural colored weft with a subtle grey cast over heavy white core yarn, these jeans will evolve into a remarkable vintage blue with contrasting fade patterns. Finally, it's topped with a dyed leather patch, heavy duty canvas twill pocket bags, embossed copper riveting on the front pockets, hidden rivets on the back, a button fly with interior selvedge detailing, and a chainstitched waist, seat and hem. This garment is comfortably slim with a refined and dutiful build, perfect for the gent who reads his history yet lives in the present. Built for the motorcycle community and over-engineered to start, Iron Heart tests the limits of what actually can be artfully woven and sewn. In short, the Iron Heart 555S in 14 oz. Selvedge Denim will comfortably and tastefully evolve into your favorite pair of slims.

Iron Heart 555S-142 Denim runs slightly small and we suggest sizing toward your actual waist size since this denim is sanforized and once-washed, and is considered pre-shrunk. Expect 1" of stretch in the waist with regular use, and shrinkage to original size upon washing.

We recommend consulting our Sizing Guide and using our Virtual Size Chart.
