Description
The Iron Heart IH-555S-SBG is a mid-high rise Super Slim Fit with a roomy seat, moderate thigh, slim leg, and narrow hem. This jean features a signature 21 oz. heavyweight, sanforized, and once-washed right-hand twill Japanese Selvedge Denim, woven on a vintage shuttle loom in Kojima, Japan. This material is made from two twisted yarns to add bulk, with a low-tension weave that becomes amazingly soft with a natural drape while retaining its form. A hallmark fabric within the Iron Heart collection, this 100% Cotton denim utilizes the dual yarn method to produce a slight slub on the inside weft, which softens to the body and gives this remarkable heavyweight denim unmatched wearability once broken in. This is a fade-to-grey denim with a specialty black sulfur-dyed warp and a non-fade black reactive-dyed weft that will yield a beautiful patina after enough road trips and concerts. Finally, it's topped off with an ultra-heavy natural vegetable-tanned embossed 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. The result is a project piece with an edge, perfect for the gentleman who likes to send a message without saying a word. Built for the biker community and over-engineered from the start, the piece tests the limits of what can be artfully woven and sewn. For a pair of jeans that read “back off,” try the 555S-SBG in 21 oz. Superblack Fade To Grey to set the tone of your look to a deeper shade of dark.
