PMG Nerekhta - The PMG (Russian: Противогаз Малогабаритный — "Small mask") was designed in the Soviet Union during the Cold War. From 1963 to the late 1960s the PMG kit was first issued to officers, paratroops and artillery crew.

Feel free to experiment with tags like "gas mask filter", "lenses" and etc.
Girl-version of this mask sometimes has cutout for hairs. Also feel free to try.

Sometimes it may turn out to get a result without a filter for a gas mask, in this case you can try adding a filter to the prompt additionally.
Sometimes, when its vertical images, the head or the mask itself may be deformed or stretched (mainly when generating portraits) - in this case, it is better to generate 1024 x 1024, and then use the picture extension.

Have a great generations! <3
