Our swimzi (onsie) is unisex and generously sized for a swimmers physique. It is designed to be worn loose with a slouchy, relaxed fit. If you would prefer a less slouchy fit, or you are falling towards the very lower end of a sizing bracket in height, we would advise to go down a size.

Unisex SWIMZI – 70% cotton, 30% polyester – 320gsm luxury peached premium cotton-rich jersey.

The beauty of the Swimzi is the flexibility of how you wear it – zipped high, zipped low or even with the arms tied around the waist, so 90’s!

Made from super soft, premium cotton-rich jersey the Swimzi is a must-have for travelling to meets, throwing on between races, or eating pizza on the sofa… once on rarely off…

The trademark SWIMZI is how it all started for us, it comes with a full-length zip, zipped pockets and kangaroo pouch.

SWIMZI sizes are generous, please consult our size guide if you have not tried one on before. If you are falling at the lower end of a size bracket, we would advise you to get the next size down.
