Typically Tilley in design, Kids Toppers' fabric has the highest certification of UPF 50+. This hat has a wide brim specifically designed to protect a child's face, ears and neck from the sun's harmful rays. Made from 100% pre-shrunk cotton for easy machine wash and dry. The reversible pattern allows for two hats in one. A tuckaway quick release chin strap ensures the hat stays on when you want it to. The quick release strap will come swiftly apart if the hat is tugged. If the strap isn't needed, it can be attached to a loop inside the hat to keep it safely tucked away. The chin strap only works on the print side of the hat.
