Hi there. Going about trying to get a gasmask for me and the lady friend but it wasnt as easy as I was hoping. There arent really as many shops selling as much as I would have thought so im having trouble finding a product. REGULATION - S10 Gas Mask - Gas Masks & Accessories - Head Gear is the cheapest thing I could find for the quality that I want which is a bit pricey.. So should I be looking online? Or should I go check out some local army store or something and pick one up there? (its got to be something that you can actually restrict breathing in). Annnnnnd if I resort to the above mask, with the tubing, what kind of stuff can I attach to it to COMPLETELY cut off air? Looking for more of an on/off type thing rather than a restriction. Internet isnt helping me much so I figured id ask the experts

Thanks for the help!!!

(sorry if this is in the wrong place!)
