Outdoor Research Voyager Rain Hat (junior)
A fabulous rain sombrero for kids. The wide stiff brim gives great protection and the hat is made of waterproof breathable fabric so it doesn't get too clammy. Magnetic attachments hold the brim up when needed and the hat floats. The cord will safely break away if tugged too hard.
To fit, measure around child's head where the hat would sit.
