A hair band is multifunctional. You can use hair bands while running as headgear, neck warmer or just as a sweatband. In the summer you can effectively use it as a sweatband, while in the winter it can function as a hair band for extra heat. There are wide and narrow hair bands. An advantage of broad hair bands is that it also covered your ears and forehead as the temperatures fall to the freezing point. Summers, on the other hand, a hair band can prevent sun rays or even a solar stroke. Come by in the store or order them online via AthletesSportsSworld.com!
