DO NOT USE THE FILTER
Soviet GP5 gas masks are arguably the most recognizable gas masks ever. Seen in movies, video games, cosplayers, reenactors, and more.
 
First issued in 1962, and production stopped in 1990. Not only did the Soviet Union use these, but many of their satellite states did so too, such as East Germany, Bulgaria, and Albania. As well as used by other Soviet allies such as Cuba.
Made of rubber latex, these are designed to be worn over the entire head, leaving just the back of the head exposed.
The number of GP5 gas masks was 3 times more than that of the population of the Soviet Union, making it one of the most plentiful gas masks available today.
 
Available now is the kit, which comes with the mask in your choice of size, a filter, and a carry bag.
 
ASBESTOS: The filters used for these gas masks do contain asbestos, therefore it is dangerous to breathe through the mask using the filter. It is not advised that you use the original filter. The masks are perfectly fine after a warm gentle wash but if you want to use a filter, find a safe-to-use filter with a 40mm thread.
