All about Gas Mask/Respirator sizes

I get frequently asked by viewers what size gas mask they should order?
This is something that is fairly complicated, as most masks use different sizing types, people have different shaped heads and often mask manufactures don't publish a sizing guide.
Soviet masks use a size system that goes from small to large. Where as some NATO nations use a large to small size system.
Other nations use a small, medium, large method and some masks use multiple parts that are individually sized.

Hopefully this video will give you some information to make an informed decision regarding choosing a good size mask to fit your head.
