I'm almost 6 4" about 210 and I went with the XL.it fits great with a long sleeve underneath.sleeves aren't too long and it's not cropped. Hits just below my belt line. It' feels a lot nicer than the pocket sweater baby alpaca I have from last season.
I stopped by the Nike stadium store in Frankfurt. Selection on the running shirts was limited. They had one color of the wool dry fit shirts. one size in the flyknit racers of the blue colorway. the sports wear section was decent. Picked the tech sweat pants. the had an fsr.
