NICE FABRIC, good sizing
Size: X-Large, Color: Black, White, Blue
These shirts are nice and long, which I appreciate being over 6' tall. I am always reluctant to buy any shirts that are not tall size, but these are long enough to solve that problem. The fabric is soft and comfortable... a good price for good shirts.
