Hello Happy Water Babies! Hello Bello’s Swim Dipes keep it in – in slim-fit style. Our swim diapers' premium leg cuffs keep it all in, and the compact core means no balloon butt. Our high-integrity bonded fiber core prevents swelling (no ballooning booties!). And the long-lasting, comfy fit stretches and flexes with your wriggly little swimmer – making it feel more like swimwear than a diaper. Our advanced leak guards are extra thick for maximum containment and the quick-tear sides mean pool-side changes are quick and convenient. Plus, they’re hypoallergenic and made without latex, parabens, or phthalates.
