Microfiber is softer, finer, and more absorbent than any other conventional cloth available today. It’s preferred for its lightweight super absorbency and rapid drying properties. The secret of the microfiber cloth is its state-of-the-art matrix of thousands of tiny fibers; 10x finer than silk and 100x smaller than human hair. These high-performance cloths attract and hold up to 7x their weight in dirt, grime, mildew, etc.
