The Iron Heart IHJ-114-BLK Chore Jacket is an improved, modern version of the workwear original that's designed to be a heritage statement piece. Produced in a 7 oz. dutiful Oiled Japanese Poplin woven with an uneven warp to weft and treated with a mixture of urethane and paraffin oil, the result is a water-resistant fabric with a dry waxed feel and vintage hand. Taken from the classic mid-century industrial work jacket, this pattern features a modified body for a tailored riding jacket and comes fully lined with a fleece body and quilted satin sleeves for a medium weight, insulated outerwear piece with reconfigured pocket placement aimed at better composition and fit resulting in modern-styled grit. Created to be a functional fall through spring outerwear piece, the Oiled Chore features a black corduroy collar, patch flap front snap chest and large lower pockets with side entry, an interior chest pocket for various tools of the trades, adjustable snap gusseted cuffs, a snapped front placket, and is completed with brass snaps, corduroy pocket and cuff trim, internal felled seams, and chainstitched construction throughout. This 114J Chore Jacket strikes the balance between climate and culture appropriate, making it a year-round go-to for a look that will take you from the workshop to wild nights. Built for the biker and over-engineered to start, this jacket will deliver a lifetime of durability in an unmistakable design.

Iron Heart Outerwear sizing is graded in small increments, and the 114J-BLK generally runs true to Iron Heart sizing. To accommodate layering, consider going one size up from your common Iron Heart size, or the larger size of your range. For a tailored fit or to wear with just a base layer, consider going with your normal or the smaller of your Iron Heart size range.

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.
