These sun hats are a fantastic deal!  They are high quality.  The adjustable strap fits a good size range of head sizes, and keeps the hat from blowing off.  We recently spent a very windy day at the beach and the hats never blew off, and helped protect little faces from the blowing sand, as well as the sun.  The hats have flowers on them that turn purple in the sun, which my kids think is a pretty neat trick.  The 2-pack for the price is a great deal!
