What's better to wear, short sleeve shirts or a tank top?

A tank top is the best thing to wear when you're going out for a run. It's light, let's your body breathe, and is comfortable. A short sleeve shirt is baggy and can become a bother. It also traps all the heat making it feel hotter than what it really is. If you are having a long run, wear the tank top, if you're doing a short run or a track workout (because it is short), wear a short sleeve shirt.These are the best times to wear these kinds of shirts.
