...not done yet!  I talked to Pete Drago (I think his name's Pete...oh well) back when I thought I was going to buy one, and he said this about their sizing on me - I was about 5'10 and 170 at the time:
"If you want it to fit loose but not too baggy, a large is perfect. our xl would hang longer and pretty gangsta, and a xxl would be a dress on you. All of our jackets run taller than standard so they will hang a little longer than your other hoodies."
Jea.
