Everyone misidentifies these as Polish MP5 gas masks, but they are actually a French ANP-VP F1 gas mask. The Polish MP5 is a licensed copy of the French ANP-VP F1 and can easily be identified by the slotted radial design of the center voicemitter cover, rather than the holes of the French ANP-VP F1 as you can see here. There are a few other differences as well, that’s just the easiest way to spot if they are French or Polish.  Most every website and eBay/Amazon incorrectly identifies these masks as Polish MP5’s. They don’t know their gas masks!

These French gas masks come in four sizes: Small=4, Medium=3, Large=2. Extra Large=1.  A small would fit most teenagers and petite women, the extra large for those with very big heads or obese individuals. This listing is a #3, size medium.  Check the other listings to order the size you want. 

These masks are used French military surplus in good condition and come with a sealed 40mm NATO NBC cartridge, the most universal filter for gas masks around the world. There is a large voicemitter in the center which makes it easier to be understood when talking.  The panoramic view window may have some yellowing with age.  These masks have an integral drinking straw/hydration system, but does not include a hose or canteen. 

The bag is a rubberized canvas with main center compartment (with multiple pockets inside), two large side compartments, and two nylon webbing straps with MOLLE compatible clip attachment hooks.
