Canadian Military C4 Gas Mask
In my opinion one of the cooler looking Gas Masks out there. Hailing from Canada ; apparently there is some issue with "non-functional" masks being sold on Ebay and such. For whatever reason this batch that got the "Un-Approval" rating by the government were all GREEN. So Buyer Beware. Others have said they have not seen the functional mask on the "public" market. But I have no idea how dated that person's info was. Regardless I think its still very cool looking.
