Baby swimwear made for more than swimming

The UV Defender Onesie is designed for parents who want versatile sun-safe baby clothing that can keep up with real life.

Wear it as a baby swimsuit for swimming and water play, then keep it on for the rest of the day as a lightweight baby sunsuit. It’s also ideal for beach days, boating, fishing, camping, holidays and everyday adventures outdoors.

Because little ones don't just spend their day in the water. And we don't think they should need a separate outfit for every part of the adventure.
