The OneSea Mermaid is a children's buoyancy aid swimsuit that replaces three separate items in one easy zip. Built from 84% polyester and 16% elastane with layered EPE foam panels sewn directly into the chest, it holds young swimmers in the correct position in the water while UPF 50+ fabric and an integrated hood block 98% of UV rays across the whole body. The mermaid-scale print in lilac and pink, complete with a fin hood and frilled ankle cuffs, makes the suit genuinely exciting to put on.

Sized for ages 2 to 3, this children's buoyancy aid swimsuit arrives in a reusable EVA tote bag that doubles as a beach bag between trips. The buoyancy foam panels are removable as children grow in confidence, allowing the suit to transition into a standard UPF 50+ swimsuit for ages 3 to 4. A front zip makes dressing and undressing quick even on a wriggly toddler, and the suit hand-washes in warm water. All use must be under constant adult supervision – this suit is a buoyancy aid, not a life-saving device.

Frequently Asked Questions

The built-in buoyancy panels are certified to EN13138-1:2021, the European water safety standard for swimming buoyancy aids. This is the same standard applied to armbands and swim vests, so the float function is independently tested rather than decorative. The suit is a buoyancy aid only - it does not replace a life jacket and must be used under constant adult supervision at all times.
The EPE foam panels are designed to be removed once a child has built confidence in the water, typically around ages 3 to 4. Removing the inserts converts the suit into a standard UPF 50+ swimsuit, extending its useful life beyond the buoyancy-aid stage without needing a new purchase.
The fabric carries a UPF 50+ rating, blocking 98% of UV rays across the full body including the arms and legs. The integrated mermaid fin hood covers the top and back of the head. It does not extend over the face, so a child-safe sunscreen is still recommended for the face and any exposed skin.
