OneSea Mermaid 3-in-1 Children’s Buoyancy Aid Swimsuit – 18 Months

The OneSea Mermaid 3-in-1 children's buoyancy aid combines a UPF 50+ full-body swimsuit, a built-in protective hood, and foam buoyancy panels into a single zip-up suit – so there are no separate armbands to pack, no sun hat to chase, and no guesswork at the poolside. Made from 84% polyester and 16% elastane with layered EPE foam inserts. The ruffle-hem and mermaid-scale print make it a firm favourite with little ones, while the full-length front zip makes dressing quick and easy at the beach or poolside.

For children who are building water confidence, the OneSea Mermaid 3-in-1 children's buoyancy aid keeps arms unrestricted so natural swimming movements can develop. The integrated UPF 50+ fabric – hood included – blocks 98% of UV rays across the whole body, removing the need for a separate rash vest or sun hat. Buoyancy foam inserts are removable for ages 3-4 years as swimming skills progress, and the suit packs neatly into the included reusable beach bag. Always use under constant adult supervision; this is a buoyancy aid and not a life-saving device.
