The 412-BLK runs true to Iron Heart sizing and is made with a once-washed, unbrushed flannel fabric. With regular use, one can expect up to .5” of shrinkage in the chest over the long term. Our Method of measuring is different than Iron Heart’s, and we recommend consulting our Sizing Guide when purchasing. We provide garment-specific measurements taken in-house, per Our Method, that are not duplicated across fabric or colorways and are re-measured each production run.
