Kids’ Swimsuits

Our kids’ swimsuits are perfect for splashing around on the beach or swimming in the pool. We have special Sun Smart materials to protect delicate skin from UV rays, plus quick-drying and chlorine-resistant fabrics to ensure our swimsuits stay soft and stretchy for longer. Choose from vibrant colours and bold prints – all with handy free store collection
