Days at the beach have never been more fun, thanks to the Stien Swimsuit. Featuring a built-in UPF 50+ factor to protect your little one, this pull-on swimsuit comes with a lovely lemon embroidered embellishment. UPF (Ultraviolet Protection Factor) indicates how well the material protects against UV radiation. UPF 50+ means our swimwear offers a very high protection factor of up to 98%, ensuring optimal skin protection without compromising style or comfort.
