I ordered the large going off of 1) I wear a lg in every shirt I own 2) thats what the sizing chart said to order. Wow, that was a huge shirt! fit like an xl/xxl... Sent it back, went to a couple of local stores that carry this shirt, and re-ordered a Med, perfect fit (Im 5'8" 185lbs)...

The shirt itself is everything it says it is, I will be ordering more...
