Oh man...if this works, it will be fantastic.

I'm 6'5" 220+ lbs. If I can't find a tall size, I have to get a XXL which is made for chubby guys, not tall thin (well not as thin as I used to be :-) ) men.

A good fitting shirt is the hardest thing to find. Pants already come in a variety of sizes (length + waist) so it's not as big of an issue.
