I bought the hat so that my head could stay cool and the brim would keep the hot Albuquerque, NM off my face. It rolls up like a dream and it adjusts with the velcro at the back. I do wish it could have a small chin strap on it so it wouldn't blow off one's head when a strong wind comes up. When I run after the kids, it sometimes slips a little off my head. But, it's not a running hat! Otherwise, it's pretty good!
