Because these shirts often are form-fitting, I ordered up a size. That's a mistake with this shirt. For example, if you wear a large t-shirt, order this in large. It's comfortable. It prevents sunburn. It dries quickly. My only complaint is its tendency to develop snags. I probably should have expected it in a polyester shirt, but I had hoped it would last more than one season before the snags and similar blemishes started showing. It should be noted that I worked it pretty hard, but I have other shirts that kept up a little better. That being said, I still plan on using it again next year and do not anticipate any significant additional wear and tear. The few blemishes from season one are not obvious, but they are there once you start looking.
