The Splash About soft white cotton nappy wrap, with embroidered logo, forms part of the Splash About environmentally friendly nappy system. Though the Happy Nappy works perfectly well alone it is easier to clean up if a liner of some type is used inside so we have developed a system to save you money and to protect the environment. The liners wrap around the wrap and are used like a regular nappy. If accidents occur simply remove the liner and put it in your nappy bag! Very little mess or smells
