Clothing is the most effective method of sun protection and pediatricians do not recommend chemical sun screens for children under the age of 2. We agree and would actually push that number up to 5 years of age or older. Afterall, do we really know what the long-term effects of chemical sunscreens will have on the bodies of our children? We really don't. Protect your kids from the sun and from unnecessary chemical burden with the poncho that protects the head, shoulders, neck and torso. Made of high-tech UPF 50+ fabric for wet or dry fun. Not meant for swimming.
