Pop Up Rain Hats are very similar in design to the Sun Hats, but they're made of waterproof nylon instead of cotton.
They have a wide brim to keep you dry, and they twist and fold into a convenient 6 inch pouch when not in use. Ideal for carrying in a bag or pocket to help you cope with rainy day blues.
Available in two sizes - Child (13" brim - age 4 to 8) and Adult (15" brim - age 8+).
The Children's Pop Up Rain Hats measure about 21 inches in circumference at the base of the crown (around the forehead) and then taper to about 16 inches at the top. Generally, this makes them suitable for quite small heads - typically 4 to 8 year olds.
The Adult Pop Up Rain Hats measure about 24 inches in circumference at the base of the crown (around the forehead) and then taper to about 18 inches at the top. Consequently, they are described as 'one size fits most' because they will just sit slightly higher or lower on your head (depending on the actual size of your head) and the soft nylon fabric helps them to conform to the shape of your head.
