I'm about 6' 195lb and the XL fits close but not too tight. The shirt is a little longer than it needs to be for running, but lets it easily double as a cycling shirt. Functional and nice look. The "burnt" yellow is kind of cool for fall.
My only complaints are that the sleeves are too long. This is irritating--when I run and the sleeves are draping down over my fingers. Wish you could cinch tight the sleeves or maybe if they had thumb holes so they were designed to hang so low. I'm a heavy sweater (even in the cool air) and this shirt seems to hold the sweat rather than stay dry. Regular price is a bit on the steep side in my opinion.
But overall, I'm glad I bought the shirt and would so again if it was at a significantly reduced sale price.
