Yes, I did see that it was a roll-up visor.  But, it's really weird!  I drive a convertible, and typically I wear a golf visor to keep the sun from shining down behind my sunglasses.  Golf visors have those nice hard bands that go around the head and keep the hat in place.  Unfortunately someone stepped on my visor and cracked the band, so instead of driving down to the nearest golf shop I just ordered this from Amazon.  One thing I'd liked about the golf visors was the ability to put them on and then slide them up, so my long hair would be above the level of the hat, and not be blowing in my face while driving.

This is a floppy hat, which is not formed into a hat shape.  It's like a long, shaped piece of fabric, which you have to join together to close using a piece of attached velcro.  Since it is floppy, I can't use it to push my hair up above the level of the hat, which means I get serious hat-head from where it pushes my hair down.  It also flops around a lot in the wind while I'm driving.

The only time I can see this being useful for me is on a trip...except that I already own several nice travel hats from Gottahavahat.com and don't need another one.  But it's pointless to return this at the cheap price.  I'll save it for something, I'm sure.
