Carbon technology bedsheets are 25% thicker and absorb twice as much liquid as conventional sheets. Each pad has 5 layers designed to keep your floors clean and dry. The upper layer is made with carbon technology, which provides maximum absorption and quickly eliminates odor. The mid-layers help to turn liquid into a gel that holds more liquid than regular diapers. The bottom layers are made of high durability that prevents the wear and tear of the diapers, which protects the diaper from leaking on the floor.
