Not exactly a real deal but it's an airsoft full face mask designed as a Russian Gas Mask and the air filter is actually a ventilation fan. Now, how it can protect your very pretty face? Airsoft Atlanta, which has the mask in stock, puts it through a stress test with teh VFC HK417 AEG... "What happens when you fire the HK417 airsoft gun at the new and improved Russian Gas Mask? It holds up just fine against 425 FPS at full auto."
