We vacation in Aruba every year and since its about 12 degrees from the equator you have to be extremely careful of your skin.  I bought this for my granddaughter - also bought her one last year and will continue to buy them since they protect her very pale skin.  She also wore a hat and sunglasses.  She was totally protected and enjoyed herself immensely.  I am very pleased with this sunsuit.  Get the one with the long sleeves so you don't have to put sunscreen on their arms - you'd just need the sunscreen on their face, ears, hands and feet.  One less thing to worry about ........... you won't be disappointed.
