The Lassig Splash & Fun Swim Diaper + Hat - Sun - 12 Months combines full sun and leakage protection so that little ones can splash, swim or play on the beach without interruption. The set features a swimming diaper with a moisture-absorbent lining and padding system. This system traps moisture in the inner lining and directly transports it outwards over a large area to keep your baby's skin as dry as possible. At the same time, maximum wearing comfort is ensured by high-quality materials, seamless fashioning in the seat area, and a perfect fit. A matching, reversible sun hat is also included. This two-piece set also features 50+ UV protection to protect sensitive baby skin from sun rays in conjunction with sunscreen.
