This is a nice looking hat for outdoor-type events or just gardening.  The inside "sweatband" is really a pad on velcro that's only in the front.  This probably makes it washable but isn't what I'd call a "sweatband".  I haven't quite figured out why it has the "adjustable" closure in the back - it doesn't really get any bigger.  Perhaps it works well for those with smaller heads.

I wear a larger than usual women's hat size (23.5"/59.7 cm/size 7.5 or XL) and this hat sort-of fits without the sweat pad but not with it.
