Excellent value, not too short
My husband is 5'11" and 200 pounds and typically wears a Large or X-Large (leaning more toward X-Large for waist, upper arms, and length). Based on the size chart, we got this in 2XL, and it fits perfectly. He has a long torso and likes to tuck in this style shirt, so length is often an issue, but not with this shirt. It is just the right length. It fits well around his chest, waist, and arms, too - just the right amount of looseness without looking sloppy. The fabric is not cotton; it is that sport material. It's just okay. We got the black, and it is like a heathered black or a super dark heathered gray. It almost looks like it has little metallic flecks in the photos, but in person, it doesn't look that way. Don't worry about it being flashy!
He would never usually wear a 2XL, so I would say these run small and to size up 1-2 from your usual size. Most of all, though, follow the provided size chart.
