Comments about Israeli Childrens Gas Mask w/ Filter:
I enjoy this mask quite a bit. It'll do its described job just fine. However, it is a CIVILIAN gas mask. Shouldering/aiming a rifle is very difficult with this mask on, handguns are fine though.
I did NOT buy the gas mask here, but at a local store for much cheaper. It included only the mask, filter, and drinking tube. I don't know exactly what this one includes.
Also, this gas mask will fit literally anyone who's face is big enough to fill it.
Example: I still wear child size hats and it fits perfectly. A 6'7" 270lb friend of mine (who couldn't play high school football because they didn't have a helmet big enough for him) can also wear my mask and it fits him just as well.
