This is suppose to be for 3-4 year olds, but my not even 2 year old had trouble keeping it on her head, her curly hair kept pushy it off. even with the strap which kept falling off it would fall backwards. Their isn't enough "height" or depth to it to fit on her head. The strap doesn't make any sense, it has velcro on one side so you could pull it off, then it just dangles their, pointless really. It never stays on, I have to sew it. I also had to remove the top fabric part and make it more of a visor to fit her head!  It now works, but a visor isn't as protective. Curly hair toddlers should get the regular girl hats, even though its a little big, it fits my toddler way better as the depth is deeper and the rim is wider. still love coolibar, but they need to work on this design a little more. Very good quality otherwise, would buy their products again.
