THE ULTIMATE GOLF HAT was invented by Keith B. Spark primarily as a safety helmet to protect the head from golf ball impact. Its visor and helmet are crafted AS A SINGLE UNIT, either from light-weight resilient plastic able to deflect golf-ball impact with minimum indentation, or from a non-conducting (i.e. electricity) alloy with similar qualities. One possible component for the hat is Enduroflex, a polyeurethane derivative.
