Our swim nappies are not designed with any added absorbency, as they will become too heavy in the water for bub - with the danger of weighing them down. So they will not replace your regular cloth nappy but are purely for water-play. They are designed to be lightweight, with leg gussets to safely contain number 2’s, but allow for water and urine to flow through. Whereas, our cloth nappies feature double-gussets which add extra leak protection.
