The best slim fit I have found because it offers an extra-small, which is good for an average male at 5 feet 8 inches and 155 pounds.  It is not at all body-hugging but I have not found any long sleeve polo shirt that is slimmer.  The material is light but strong.  The color choices exceed other vendors.  The price is a very good value, especially since I was prepared to pay double for a slim long sleeve polo shirt.
