The Iron Heart IH-777SBR-14 in Indigo Broken Twill Selvedge Denim is a mid-low rise Super Slim Tapered Fit with a moderate seat and thigh, tapered leg, and narrow hem. This jean features the new Iron Heart signature 14 oz. medium weight, sanforized and once-washed Broken Twill Selvedge Denim loomed in Kojima, Japan. This 100% cotton broken twill denim is a non-directional weave achieved by vintage shuttle looming that creates a zig-zag pattern and allows for greater flexibility and give to develop drape while retaining its form through years of wear. Produced with the signature dual twisted weft yarn method to add structure and a slub texture, this 14 oz. denim yields a unique and dutiful heritage style piece. Featuring a rope dyed indigo warp and a natural colored weft and core yarns, these jeans will evolve into dark shades of blue with contrasting warm fade patterns. Finally, this piece is 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 super 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. The Iron Heart 777SBR in 14 oz. Broken Twill Selvedge Denim will comfortably and tastefully evolve into your favorite pair of uniquely made slims.

The 777SBR-14 runs on the small side of Iron Heart sizing, and we suggest sizing to your Actual Waist Measurement (Body). Made with a sanforized and once washed denim, 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.
