THIS IS THE LATEST AND NEWEST ISSUE OF MP4 GAS MASK SO ALL OF THEM ARE IN THE LATEST WATERPROOF MODEL OF THE BAG. ALL OF THEM HAVE DRINKING SYSTEM SO YOU CAN DRINK WHEN WEARING IT. TO EVERY GAS MASK WE ADD ANOTHER PAIR FOR FILTER FOR FREE.
The Polish MP4 gas mask is a close copy of the US M17, which was copied by several countries including Poland. Since the MP4 was based on the M17, most of the accessories for the M17 should work with the MP4. It is built like that so the filter doesnt disturb shooting from weapons and makes aiming easier. Soviets were really imressed with cheek filters solution, that's why they copied and refined it.
IN THE PAST I THOUGHT THIS IS EXPERIMENTAL GAS MASK AND JUST LIKE 300 PRODUCED. THAT'S NOT TRUE.
I WAS MISLEADED BUT IT WAS EASY TO BELIEVE AS SALE OF THIS GAS MASK STARTED ABOUT 2018 AND BEFORE THAT DATE I DIDN'T EVEN KNEW THEY EXIST.
