If anyone's interested I just took some pre and post wash measurements. I have 3 other Iron Heart shirts that are all mediums but this one I ordered in large with intention of shrinking. I requested a shirt that was on the smaller side in the shoulders and arms.
The shirt was washed warm and tumbled dried hot.
| | Pre (inches) | Post |
| Shoulders | 17.75 | 17 |
| Length | 29.25 | 28 |
| Chest | 22 | 21.5 |
| Sleeve | 26 | 25 |
Fortunately it shrank the perfect amount. I love the shirt and it makes me wonder why I would buy any other brand. It's so warm it almost feels like wool.
