Designed to help your child stand out in and around the water, this bright neon one-piece makes it easier to keep eyes on your little swimmer at the beach, lake, pool, splash pad, and water park.

Baby and toddler sizes also include corrosion-proof metal snaps for quick and easy diaper changes and potty breaks, making this one-piece as practical as it is adorable.

This neon swimsuit is also OEKO-TEX Standard 100 certified and tested for harmful chemicals and substances, so you can feel confident about what’s against your child’s skin.
