I play table tennis as my fun thing to do, and, especially in summer, it isn't so much fun when you are perspiring like crazy, and your shirt and shorts are soaking wet.  This shirt is a composite or combination of cotton and a synthetic; as such, it is a little cooler than a full cotton t shirt, and more importantly the water from your body (i.e. sweat) evaporates from the shirt very quickly. Most of the time I am dry when playing. Under the arm pits is a small exception, but I can live with that.  The material is almost as soft as a good cotton fabric, and the fit is full (I wear a large as I lift weights).  The stitching seems adequate (I haven't had any parts come undone or unraveled as of yet).  As a final note, notice the 5.2 ounce as to the weight of the shirt; it is slightly lighter than other shirts on the market; this again helps it to shed water more quickly than others in the same class.  (If price is a factor, Fruit of the Loom also produces a similar shirt, often at a  lower price when found on sale.) Oh, one more thing, there are some full synthetic t shirts out there that are even cooler and lighter, the problem is they do not have a pocket.  I like a pocket on my t shirt, so this is the best one with a pocket.
