Review title is Perfect sleep or carseat cap [SEP] My daughter's hair becomes a mangled mess after a car ride or a night's sleep. These have given her a new freedom of no knots! She loves them, they are pretty, they stay on, and her hair is soft and knotted. There was a solid black one, so she wears that one under her bike helmet. The binding is incredibly soft with no seam ridges. So happy with these.
