Cotton towels absorb sweat the best if you rub them across the face. That works best for absorption, but also irritates the skin and messes up any kind of makeup someone might wear. The Dancetowels work best if they are only laid onto the skin without rubbing. That's how they absorb best, are very gentle to the skin since there is no rubbing and the makeup will (mostly) stay on the skin, where it belongs. ;)
They are made from recycled plastics and (unlike other microfiber cloth) they are washable at 60° to get rid of all bacteria in the washing machine.
