These shirts are so hugh I can swim in it. I normally wear Large polo shirts and ordered 2 large ones as well as 2 medium ones for my dad. The large ones are way way too large, at least 2 size over what you would typically find in a clothing store. Even the medium size is bit large for me, but I end up keeping it. Amazon refunded me $3.50 a shirt after taking off for the postages.The quality of the cloth is good, very airy and would serve well as a golf shirt. Just make sure to select 1 or 2 sizes smaller than your typical size.
