This Christmas light up beanie hat by FuturePlusX is really awesome. It fits up to an adult size but my five year old Grandson loved it so much we let him have it. It has three different speeds for the lights, the control for the lights is easy to use, it is in the back so all you have to do is click it several times to get the lights you desire. Not only does it keep him warm but it keeps me lite up and busy at the same time. It is made very well and we were very happy with it.
