I'm 6.2 and 205 and don't like short sleeves crowding into my armpit, so I normally go up a size so that my shoulder seam drops over the side of my upper arm by an inch or so. In this case I took the suggestions about going up a size again due to these running small?

So XL normally works and I like the shirt tail to be longer so I want to tuck them in and they will stay put!
Based on the reviews here, I ordered the 2XLT, so when these arrive the seam between the upper part of the sleeves and the shoulder rides just over the top of my shoulder, but the sleeve are still a bit short by 3/4 to even a full inch. They had a bit better fit before washing and I don't use a dryer for most of my cloths. Anyway, I'm keeping the shirts, the collar seems to be well made and keep it's shape so that's important as well.

Note: Shirts from another order were made in Pakistan and were not stated as being "heavyweight" shirts.
they feel about the same (a bit softer maybe) and yet the fitting is better with about 1/2 in more sleeve than ones from this order, which were made Nicaragua? Laying both out seam to seam and the sleeve on the Pakistan was a bit longer than those from Nicaragua, both shirts had been washed twice!

IMO - the material that is being used today vs. the past are not going to hold up as well as shirts from late 80's and early 90's which in my case held up well past 20 years or more and many were made in the USA.
