A flattering and playful style, the “Mia” has a medium width straight brim for the classic boater hat look. Pair that with the convenience of UPF 40+ to protect from the sun and you've got a winner. The "Mia" is made out of a braided paper/polyester mix and is classically trimmed with a narrow black polyester grosgrain ribbon. The shape is an oval flat top crown with straight sides of 3 1/4" deep, and a flat, straight and wired brim of 2 1/8" wide. Its base size is 22 3/4" and for the perfect fit, you can find an interior band with adjustable elastic to make it more snug.
