do you want it for novelty or SHTF.

FOr SHTF no. I get a kick out of the folks grabbing these up. IF they need it odds are it won't be with them when they do, or they won't know they need it until it's too late.

that said i have a few masks squirrled away. a 60's era m9 mask with new filters and adapter and a couple of chezch m10 masks i picked up for almost free last year. i keep one in the car because i support an army depot involved in incinerating chemical warheads from time to time.  that said by the time i knew it was a problem it would be too late to grab it.

My suggestion is get the SHTF gear you NEED for survival first. this stuff is more novelty than useful.
