It's a great idea. It has two solar cells and one fan, as it gets hotter and brighter, the fan in the centre spins faster to combat the heat.
It doesn't require much sunlight to work either, meaning it's great to wear on any sunny day really. Especially good for a hiking or fishing trip out in the summer.
Mine was broken on arrival, but I quickly fixed it up with some glue.
The solar cells seem to be of poor quality.
I might add a switch to this to be able to control when I want the fan on or off. It's easy to get to the circuit itself.
Cool hat, very practical- although embarrassing to wear. If you're going on a fishing or hiking trip on a hot day, the embarrassment really is worth it.
