A friend turned me on to these fabulous shirts about five years ago; now I won’t ever wear a cotton tee-shirt for any strenuous activity. These synthetic fabric shirts dry super-quickly, keeping you cool during intense activity. Conversely, in colder weather, the quick-drying feature keeps you warmer.
After I’m done, I wear mine right into the shower, give it a quick wash with soap, then hang it up to dry. It dries in a few hours and is ready for the next workout.
