Your little adventurer will love this hat. Take it anywhere from the mountains to the beach! Comes in Toddler and Child sizes. Toddler size is 48 cm around. Child size is 52 cm around. Each hat can size up and down two sizes. *To find out your Childs size take a ribbon or string and wrap it around the part of your child's head you want the hat to sit. Measure the string/ribbon along a measuring tape (in centimeters) and it will give you their size. We recommend sizing up if they are in between sizes.
