It looks like a bucket hat.

Bucket hats are pretty useful as far as hats go. Glad to see they have a long standing heritage!

		The great feature of the bucket hat IMO is that, unlike a wide brim hat, you can fold it down and stick it in your pocket when it gets cloudy or the sun goes down.

There’s a joke about Oasis in there somewhere.
