I bought this long sleeve polo as a test article to wear during travel or doing some outdoor activities.This shirt feels and fits similar to a dri-fit shirt. It will be slightly looser, so please keep that in mind. Other users mentioned that these run big.I am 5'9, 190 lbs, and athletic build. I ordered a medium and it fits very well.This shirt is simple but very comfortable. It would make a great golf shirt, travel wear, etc.
