My guess is that the wabash is one of the few shirt materials that is not pre-washed to remove shrinkage. Perhaps to maintain the beautiful contrast of the bleached dots? If my theory is correct, the shirt should be slightly larger than western shirts that are one-washed at Iron Heart. I finally washed my IHSH-62-IND for the first time and went for the warm 40C wash to tighten up the chest and arms. It came out perfectly. The shirt shrank about 1/4" in body length and roughly 1/8" on the sleeves and chest. I compared it to my IHSH-218-BLK (Johnny Cash III) with a tape measure and they are almost identical now with the sleeves of the wabash being about 1/8" longer than the Johnny Cash.
