Maximum sun protection and beautiful design is what we do best! Our reversible, UPF 50+ sun hats offer 99% protection from the sun’s harmful rays. Made of super soft 100% cotton, our fun designs and fabulous embroidery and patchwork details are sure to turn heads! Reversible chin straps (for small and medium sizes) keep the FlapJackKids hat secure on your child's head, even on windy days. Older kids are happy to be chin strap free! What's not to love?
