A winter shirt does not stretch as much as a summer shirt. The holes are a little tight. I would recommend increasing the size. I'm 6ft 0in 200lbs. I wear medium in a summer shirt. I went up a size for this shirt, if you have large shoulders/arms I would go up a size. I was wearing an Under Armor winter shirt underneath that shirt and by the end of an 8 hour workout at 35F I was sweaty. Very comfortable, warm and well made. worth your money.
