I have four of these and find them very comfortable and great to run in for colder temps. I may have been able to get away with a LG but don't care for too close a fit. I'm 6 ft 215lbs and these fit a bit loose with the sleeves coming to rest mid palm. I'm guessing a few hot washes and drys might, or, re hemming the sleeves, or just live with it...it's only a work out/ run shirt.
