Pretty good, not great. The brim is a decent size to block the sun, but I have to wonder why many of these rear-flapped hats don't go a bit more around the sides to block side-glancing sun? There's a long string with a clip at the end to beckle the hat to you, but the clip is metal and heavy, and shoud be a liter plastic because, unless you clip the string to the brim or hat, it will swing and slap the heavy metal lip around on your back. It's a keeper but not a repeat buy.
