These are really cool hats! Use them for party events, nighttime illumination, sporting events, or just a regular hat during the day. There are no logos on these hats, so you are free to have your own theme embroidered if you wish. Glow Hats are battery and LED operated. They come with the first set installed and the batteries are replaceable. Average battery life is 30-40 hours.
These hats are size adjustable for a proper fit. The bright blue LEDs feature 3 modes of operation activated by a small clicker inside the embroidering. They have a heart beat pulse flash, a rapid flash, and steady on.
