I bought three of theses shirts in different colors.  I was a bit hesitant at first to get three without knowing what i would receive. They arrived today, I tried them on and I love them.  I thought they might be more of an undershirt but they are a bit thicker than that which is great because they look great by themselves with a pair of jeans on. So its a great shirt to wear out at a very reasonable prize.  I got size 'Large' and I am 5'10, 185lbs, athletic; they contour my body well. Very satisfied :) Thank you!
