Size
I got an XL. Nice shirt, I'm 6' 2 about 207lbs fit a little snug, not bad though. Maybe I should've got an XXL. Good quality especially for the price. Hope this helps.

Husband now has 4 of these
Very well made, soft, comfortable, and look great! My husband liked it so much I bought it in 3 other colors because he is picky AND hard to fit. He also has long arms and these were the first shirts in a while where the sleeve length worked.
