Our Swimwear is breathable and comfortable to wear providing functionality as well as protection against the sun for your little one’s skin. These bathers are designed to feel soft and silky whilst providing stretch for comfort and movement.

This Swimwear is the perfect addition for your trip to the beach or poolside. Featuring the exclusive hand-illustrated artwork that you know and love, all of our swimwear is made with high quality, sustainable Repreve. Repreve technology rescues plastics that would otherwise make their way into the oceans or landfill and turns them into recycled fiber which can be used to give items a new life, benefiting the environment. 

All of our swimwear is soft and breathable against your little one’s skin whilst providing protection from the sun with a UPF 50+ rating. Designed in Melbourne, Australia, the Swimwear range provides you with beautiful swimwear that is also durable, functional, and environmentally conscious.
