Swim diaper and Swimshirt Set. This set completes the look and keeps the pool safe from evacuations. Our sunshirt protects baby's sensitive skin from harmful rays with UPF protection. The nageuret reusable swim diaper adjusts to three different sizes and grows with your child. At 6 months your child will have the diaper fully adjusted around the waist, snapping all the snaps to make the diaper our smallest size. The rise snaps in front can be adjusted up for a tighter fit around the bottom. This set is a great gift for new moms because you never know when a fun water play situation may occur. It fits easily in the diaper bag and is a summer essential for all babies.
