First of all these are really good shirts and the most pleasant thing is the collar, the thick and wide elastic which I like. Find out the size easily after washing. I wear medium clothing in most men's button down shirts and jackets. I use Carhartt t-shirts as the gold standard (I just wish they made collared shirts in this style). I wear a medium in Carhartt shirts and there is room. Let's say Hanes style, it's hard for me to get the same fit. I thought these Pro 5 would be big but after washing they shrink too much. So ----- I still like this style, must try XL (which is crazy for someone my height). Hope that helps.
