The Karen Keith toyo braided cloche hat is beautifully made.  The tightly woven 75% Toyo and 25% Polyester combine to make a product that looks great, and the wide 4.5" brim does an excellent job at protecting your face and neck from the sun. The 3.5" crown is decorated with an elegant bow that ties off at the back.

The inside of this hat is unlined, and has a fabric sweatband.
