The PMG (Russian: Противогаз Малогабаритный — "Small mask") was designed in the Soviet Union during the Cold War. First made in 1963, this mask was used in both the Soviet Union and Hungary during the 1970s. The Hungarian (70M) version differs slightly from the Soviet mask by featuring a higher number of smaller holes in the voice diaphragm. Beyond that, however, they are structurally identical.
The mask has two flat circular glass eye pieces, which can fit anti-fog inserts, to aid in the use of optical equipment. There is a speech diaphragm located under a removable cover on the front of the mask, and a doubled exhalation valve located towards the bottom of the mask, under the diaphragm. The mask takes a GOST-compliant filter to the side, in a thread unusually made from rubber.
The PMG has a strap at the back of the mask, its purpose being to allow a better seal, but the mask is secure on the head without its use being employed. The holes on the helmet part of the mask were made for ventilation of the head so the wearer wouldn't experience overheating.
