For all mermaids who live around us, not in fairy tales!


Swimsuit for your unforgettable vacation

Match with your little mermaid

One swimsuit made from almost 20 plastic bottles

More than 6,000 plastic bottles have already been recycled for UnderW swimwear.


Each suit is made from hight quality recycled polyester. It means that fabric is made from recycled plastic bottles and requires fewer resources than that of new fibers and generates less CO2 emissions.
