Great shirt, not the greatest fit
I bought this shirt based on other reviews saying that it was a great shirt with an 'athletic cut'. It is a great shirt, well made and good material and venting for hot, wet and sticky places like south east asia or central america.
But i tried it on and was not impressed. I bought a small, i am 5'6 and 140 and it was a tad small (short at the bottom and sleeves) but i didn't go up to a medium because it was so big and made me look kind of round which i'm not and it looked really plain as well.
I'm clearly the exception to general opinion here so maybe it's just me, but just be sure before you purchase or you'll be returning it just like i did.
