The Iron Heart IH-555S-18 is a mid-high rise Super Slim Fit with a roomy seat, moderate thigh, slim leg, and narrow hem. This jean features the Iron Heart 18 oz. medium weight, sanforized, and once-washed Japanese Selvedge Denim produced by famed Shinya Mills — established in 1951 — and is woven in a low tension weave on vintage shuttle looms using a moderate slub yarn. This revisited and evolved proprietary 100% cotton denim within the Iron Heart collection uses their signature dual twisted weft yarn method to add structure and an interior slub texture that softens to the body for a remarkably durable denim that has a natural drape and retains its form through years of wear with unmatched performance and comfort. Featuring a rope dyed indigo warp and a natural colored weft, these jeans will evolve with character-rich vintage fading patterns in a brilliant blue. 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. This garment is comfortably slim with a refined and robust 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 18 oz. Vintage Selvedge Denim will comfortably and tastefully evolve into your favorite pair of slims.

The 555S-18 runs on the small side of Iron Heart sizing, and we suggest going down 0-1 sizes from 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.
