This 2-piece set with a long-sleeved rash guard and swim diaper is perfect for little sea explorers. With built-in UPF50+, the set protects them from the sun as well as chilly, salty waters. The rash guard has a subtle textured finish and is fitted with a zip on the front, while the swim diaper has a snug fit with elastic around the legs to keep their diapers dry underneath. Made from recycled polyester and elastane, the set is gentle on skin and kind to the planet.
