I was looking for new t shirts and polos and was completely disappointed - nothing seemed to be meant for humans. If you're about 6 feet tall or more, you'll probably need the large version. I'm 6ft tall and being tall is perfect for me. I suddenly found a few and this one is amazing, especially the collar. The ribbed flat collars found on most polo shirts flatten or lose their shape quickly. This collar keeps its shape and is most importantly stylish.
