J Crew long sleeve swimsuit in cerulean, size 4-5y

All of our supercute, ultra-comfy rash guards and suits—like this long-sleeve one-piece—feature UPF 50+ sun protection (aka SPF for clothes). That's why they're recommended by the Skin Care Foundation as an effective UV protectant...but we still suggest wearing them with sunblock for ultimate coverage. Poly/elastane. Our swimsuits are machine washable, but we recommend hand-washing as it helps keep the fabric and the shape of the suit looking newer, longer. Excellent condition.
