Purchased new and used only in the summer by one child. The chin strap is removable, and the back of the head is mesh, so it was used for pools and water play. It also has a neck shade. It can be hidden away for everyday use, so it was also useful for daily wear. Size can be adjusted. Please take a look at the many images. I am listing many children's items, so I will ship them at a reduced price if you combine them.
