Fit's great. I think the cut-out design is a fabulous idea for those of us who like to wear our hair in ponytails or in buns. Everybody at work keeps laughing at me when I wear the hat with my hair down, since I suppose it looks a little bit silly with the back half of the hat missing. :)  I keep telling them it's meant to be worn with your hair up, but I think it is great anyway. And it fits my head really well.
