Stay awhile from Slimer when you get the one size fits most 100% cotton Ghostbuster Grey Snapback Cap! You wouldn't want him to ruin it...you may have to take your chances though if that ghost has some Ecto-Cooler. Yeah, that's right folks...somebody else remembers that divine liquid! Scientific proof that anything Ghostbusters related is awesome, right? The adjustable Ghostbuster Grey Snapback Cap has the Ghostbusters logo and the 'Who you gonna call' phrase on the underside of the bill. Get this hat or there will be dogs and cats living together...MASS HYSTERIA!
