Playing Fortnite for ten plus hours a day is a long time.  Some people have sweaty hands and this can cause you to lose grip of the mouse or keyboard.  When every split second counts you want to make sure this doesn’t happen to you.  Clix uses a towel to dry his hands and make sure his grip of his keyboard and mouse are perfect so he can play at his best. He has even sold towels when he was on Team Misfits Gaming, I’m sure now that he is on Team NRG they will also start carrying the product once they switched everything over.
