On my Sun smart hat it has a solar powered fan which means it is powered by the sun.It also has a button when you press the button a cloth will cover your neck and ears so you don't get sun burnt. It has a sun screen bottle attached to it as well.
It has a water bottle holder that comes with a special water bottle that you can plug a tube into the bottle so when you are running you can have a drink. The tube can stick to the side of the hat also there is a green button and when you press it a pair of sun glasses come down from front of your hat.
Weather your big or small being sun smart counts for all. Being sun smart is sun safe.
