While this shirt looks to be a plain ole cotton polo, it’s anything but. This sucker is bulletproof! The shirts are designed by Colombian designer (and safety enthusiast) Miguel Caballero and come in three levels of protection. The lowest protects against a measly 9 mm, the highest level can take a machine gun and is stab-proof. Wow, I guess things must be getting seriously out of hand over at the country club since we need to have STAB-PROOF polos. That definitely makes me nervous. Just think about it — if grampa golfing with his buddies isn’t safe anymore then who is?
