The Iron Heart IH-555S-142IB 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 an unmatched durability and performance. Featuring an indigo rope dyed warp and black sulfur dip dyed weft over heavy white core yarn, the result is a highly saturated navy denim that will fade with a high contrast in steely shades of electric blues. Finally, these jeans have tonal navy stitching for a clean aesthetic paired with signature details of a painted natural vegetable tanned 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 comfortably slim garment with a refined and dutiful build is 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. Indigo x Black Selvedge Denim will comfortably and tastefully evolve into your favorite pair of slims.
