The cut In the body and sleeves is much too baggy for athletic use (running, hiking, bicycling, etc) in cool and cold weather where you would be layering. It's way too loose to fit comforably under a sweater or jacket. Alone, it moves around my body too much while running. Also, the body is too long and the sleeves are too short. It was too inexpensive to pay for the cost for return shipping, so I kept it as a pajama top which it works very well as.
