Thank you for viewing! (o^^o) The surface that touches the skin is soft and fluffy, like felt. The back is entirely waterproof fabric. It's a slightly larger, easy-to-use size than regular sanitary napkins sold for everyday use. *This is the last of the M size currently listed. There are no plans to restock for a while. (Fully waterproof, for heavy flow days, for light flow days, for panty liners, for bladder leaks, cloth liners, period panties, warming activities, for nighttime, black, trial)
