Gunslinger Cowboy Hat with Reinforced Lining
With a reinforced band that will stop the hottest loads, the rest however, will not. It's bright as balls though, so in the sunlight in a showdown, your opponent will absolutely get sun shined in their eyes and make them aim just an inch to high and miss your head all together.
Or it's all placebo. I guess you can send us a review after your first duel. You know, if your still alive anyway.
