Umbrella Hat, Sun Rain Cap Colorful Folding Umbrellas Headwear 23” Beach, Party, Outdoor, Fishing, Hunting and Gardening, UV Protection for Adults and Kids

You can't wear this absurdity. But, this is perfect for shading my hummingbird feeders. With few modifications and zip ties, nectar in feeder stays cool even in 90F sunlight. Plus birds appreciate the shade while feeding anyways.

This is very useful for sitting in hot tubs on rainy days Your head and shoulders stay dry, but I wish it had a clip-on chin strap. It ties. I put my own clip on it and it works well for the purpose!

What start with number one these things are hideous, also for an “umbrella” why is it built upside down so that if it’s raining the rain would collect on top? The chin strap is just a tie and the dumb things blows around, not secure at all. Horrible design, ineffective.

It’s an amazing hat with one fatal flaw. It absolutely does not grab your head or stay on in any other way but by balancing. I fixed the issue by adding a harness to it with four zip ties. Now it is perfect!

So, I had to buy this thing. Kind of on a lark. It is fun. Functional? Dunno. As noted in another review, it's only held in place by a chin strap and that's not terribly great for long term use. As a sun hat, it falls a bit short. As a costume accessory, it's killer though. It is constructed like your basic umbrella hat, held on your head with a ching strap. It could use something else like an elastic band like other umbrella hats have, not that those stay in place well either. So basically, it's a bit awkward to wear, but a lot of fun and that's all I really expected out of it.
