A lot of science goes into this super-soft piece of fabric, but the biggest and most important takeaway is that it kills 99.9 percent of bacteria and germs. The idea for this innovation is based on research that we, humans, don’t wash our towels as often as we should. Moral of the story: If you’re not going to wash it, you might as well invest in a product that can clean itself and prevent that yucky dirty towel smell.
