Onesea 3-in-1 Shark Buoyancy Aid Swimsuit Ages 3-4

The Onesea Shark 3-in-1 combines a UPF 50+ full-body swimsuit, a built-in shark hood, and 16 easy-to-remove EPE foam buoyancy aids into one zip-front suit – so parents carry less and children stay safer at the pool or beach. The 84% polyester, 16% elastane fabric blocks 98% of UV rays across the entire body, while the vivid blue-and-lime shark design makes children easy to spot in busy water environments.
For ages 3-4, the 16 foam inserts are removable as confidence in the water grows, extending the life of the suit beyond the buoyancy-aid stage. A zip front opening makes getting children in and out straightforward, and the suit comes packed in a reusable EVA beach bag for tidy storage between trips. This children's buoyancy aid swimsuit replaces armbands, a separate sun-protection suit, and a hat in one – cutting down the poolside kit bag considerably. Hand wash in warm water to maintain the fabric and buoyancy foam. This product will not protect against drowning; constant adult supervision is required at all times.
