EcoNaps baby and toddler onesie swimsuits offer incredible comfort and protection for your little one.

From early morning paddles to sunset sessions, your little one will look the part in our easy breezy One-Piece swimmer.

With UPF 50+ sun protection to protect delicate skin, a zipper at the back for easy dressing, and crotch snaps for quick diaper changes (and toilet breaks), our swim onesie is a summer essential. Pairs beautifully with our swim hats and swim diapers.

Proudly designed by ocean lovers in Australia.
