OneSea Mermaid 3-in-1 Children’s Buoyancy Aid Swimsuit 12 Months

The OneSea Mermaid 3-in-1 is a children's buoyancy aid swimsuit that replaces three separate items – armbands, a sun hat, and a swimsuit – with a single zip-up garment. The mermaid-scale print in lilac and pink covers a full-body UPF 50+ fabric that blocks 98% of UV rays, while the integrated hood protects the head and neck without a separate hat. Layered EPE foam panels built into the chest provide buoyancy, parents can rely on it as a certified swimming aid rather than a novelty. The suit is sized for 12 months, crafted from 84% polyester and 16% elastane, and arrives packed in a reusable blue tote bag.
At the beach or pool, this children's buoyancy aid swimsuit keeps things simple for parents and engaging for little ones. The front zip makes dressing and undressing quick even after a swim, and the ruffled ankle cuffs add to the mermaid look children love. The buoyancy foam panels can be removed for children aged 3-4 years as water confidence grows, meaning the suit continues to earn its place in the beach bag long after the earliest pool visits. Hand wash in warm water to maintain the fabric's stretch and UPF rating. As with all buoyancy aids, adult supervision is required at all times – this suit is a swimming aid and does not protect against drowning.
