LanzomWomen Wide Brim Straw Panama Roll up Hat Fedora Beach Sun Hat UPF50+

Can you roll the brim up?

Does anyone have any thoughts as to fit? I have an average size head, but massive, thick, long hair. Think it'll fit me?

Is the band removable?

The description says you can adjust by means of a velcro strip but others say it is a string that ties-which is correct?
