Without knowing what they used, your best bet is going to be a refurbed milsurp mask. New filter cans and everything.

Russia

No such thing as sleep gas?
That part might be a problem.

Anything that will knock you out will probably kill you shortly after. That is why the anesthesiologist sits there monitoring you while you are knocked out in a clinical setting. Everything they might give you is not far from killing you dead.


Fine, fine, whatever.
Be batman. Use your BatSleepGasBlockingMask.

He's russian, and russians have a history of dealing with criminals using sleep gas.
Not a good history, but a history.

That's why he wants a gasmask capable of (hopefully) blocking whatever it is.

Some protection is better than no protection.

Problem is, most filters are specific to each gas/contaminant.

'Sleeping gas' in the context of robbery is most often carbon monoxide. However, most 'sleeping gas' robberies have turned out to be false. 'Filters' are impractical for this.

However, a carbon monoxide alarm might be worth it to wake you up and start a ventilator. So long as you can get fresh air in, you'll be fine.
