I think it's safe to say that this Hazmat Hazard Costume guy has obviously been through the ringer. He's somehow flammable, radioactive, a biohazard, and poisonous. Wow. That's like Zone of Exclusion deadly. If you bottled up Chernobyl, you'd still have throw a few more things on top of it to get it up to the kind of deadly that this guy is packing. It wouldn't even come close, otherwise. A zombie virus might be the one thing this guy is missing, but looking at this face, I'm not sure he hasn't already become a member of the undead.
The Hazmat Hazard Costume comes with a jumpsuit (with a hood), a vinyl mask, gloves, and mesh printed sleeves. Whatever you do for Halloween, though, just make sure you don't go rushing into a nuclear meltdown or an overturned military biohazard tanker, because you've seen what it did to this guy (and he's a professional).
