This is a swim diaper and bathing
suit in one. Wear it alone or under a swim suit or swim trunks. Do not
add anything to the inside; you do not want a swim diaper to be
absorbent - it would just absorb pool water and could weigh the child
down. The design is based on containment. Make sure it fits snugly
without leaving red marks. When you get out of the pool, make sure to
put on an absorbent diaper to prevent accidents.
