Jeremy L.wrote a review of Patagonia Bucket Hat on July 4, 2010
It does the job, keeps the sun and rain out while keeping your head cool. Mine came very crumpled, enough that I needed to use an iron to heat it so the flap stays up (imagine folding a paper plane, then straightening the paper again). But you easily can fold it and put it in your side pants pocket and still keep a low profile.
Maybe it was just my hat, but my bucket wasn't as buckety as I would have liked it to be and the flaps didn't extended as far out as I would have liked it to be either. If you really want a sun hat, then find one with a good flap area. I would recommend one to you, but this review is about this hat.
