I'll start by saying I'm 5'7" weighing in at an all time high of 180lbs and I ordered a Large. (Thanks quarantine!) This shirt is thick like the old school rugby shirts we bought when I was younger. The material feels nice against the skin. The length hits right at my hips. I'd buy more if they had different patterns. I'll probably research that next. If you're on the fence, go ahead and buy it.
