Ok tee shirt for the gym. I'm 5' 11'' and 200lbs : I got the large size : The sleeves are a bit long for a running shirt --- this is because are a while on the treadmill, I'm sweating and the shirt gets heavier as the shirt retains some of my sweat ... I feel like I need to hike up the sleeves a bit ... I don't like this aspect of the shirt ... I wouldn't want to run any long distance in this shirt ... not only because of the sleeve length, but also because the shirt feels fairly warm.

Overall build quality is very nice.
