Although listed with a headstrap (and I was told by a company representative that these sunglasses did come with a strap) - beware. There is no headstrap. Could really use one. The earpieces curve inward to try and stay on, but don't work as well as a headstrap. The lenses are easily scratched which is a disadvantage for kids sunglasses.
Beware also that the kids sunglasses are usually "out of stock" and it takes 6 weeks minimum for you to get your order.
