The Iron Heart 555N in Natural Indigo is a down to earth craft piece in a high rise Super Slim Fit with a roomy seat, moderate thigh, slim leg and narrow hem. It features a medium weight, 17 oz. sanforized and once-washed right hand twill Japanese Selvedge denim. A softer and more flexible pick from the Iron Heart collection, this fabric is made from organic cotton with subtle weave irregularity, produced on a vintage shuttle loom in Kojima, Japan. Featuring a natural indigo dyed warp and an unbleached beige colored weft, the jeans have a deeply-set in dye meaning they will patina dramatically for the patient, loyal and true. 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 pure and rustic appeal, perfect for the gent who reads his history yet lives in the present. Built for the motorcycle community and over-engineered to start, it tests the limits of what can actually be artfully woven and sewn. The Iron Heart 555N in 17 oz. Natural Indigo has enough character to rival its wearer, yet will tastefully fade with a considerable amount of off-road adventure.

Iron Heart Denim runs slightly large, and we suggest sizing down roughly 1-2 sizes from your actual waist size. 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.
