Protect your hats, my friends. Your hat is your most vulnerable area in a gun fight, as we learned from this scene in Experiment 511 - Gunslinger. It seems unthinkable to us now that cowboys in the Wild West wouldn't make or buy a simple hat protector to safeguard their lives, but the historical record is indisputable. Thousands of unfortunate souls met their demise with a bullet straight to the hat.
Far fewer people wear hats these days, but if you choose to go down that path we suggest you also buy a helmet to put over top and cover it completely. It's the safe and responsible thing to do.
