Wearing stockings can reduce the skin wear during fitness running or some anaerobic exercise training, especially when running, you will sweat after a long time.

If the sweat evaporates with the wind, you will catch a cold easily after a long time. Sweat absorption can be achieved with silk stockings, and then I accidentally fell down.
