Absolutely love my Black Hawk shirts. I bought a size up as I always do when I can't try them on. I'm 6'4 with a longer upper torso, and shirt tend to shrink and then they are too small. I bought a 2x, washed them and they fit perfectly!
I got this one as a bonus with my purchase and it's one of my favorites. Absolutely love this company and the clothing. Top notch.
