Can you buy these?
Can't find any on eBay, bummer.
Aren't these what they call "re-breathers"?
I like how it just casually mentions if any water gets inside it'll catch on fire and kill the diver :v:
It's an IP-5 rebreather, not really a gas mask.
If I remember right, it was originally given to tank crews so they could escape if their vehicle sank or got stuck whilst fording deep water.

Yah that shit had me worried when he took the mask off in water and I was wondering if that was fucking safe.
I can't even imagine what a underwater explosion/fire would look like that would kill you.

For a casual diver this would be inferior to a standard SCUBA gear set. Like the video mentions, it's for military divers. Maybe shallow cave diving as well, but that mask would be atrocious for cave diving.
The video seems to imply that the catalyst releases pure oxygen which results in your maximum depth being [I]very[/I] limited; bad shit starts to go down if you go in deep water with pure oxygen.

i'm assuming the areas where air is kept is where the fire would be. so you'd basically be internally on fire at first, and i don't think the fire would burn through the mask (unless that second-grade shit with the fire and paper cup filled with water is not to be believed or doesn't apply in this situation.) otherwise, it would burn, the bag would break, and you'd suffer some serious burns and wouldn't be able to breathe cause you'd be underwater. no wonder they don't commonly use this :v:

I was more worried he took off the mask and water could get through the intake unless that thing is more sophisticated then i'm giving it credit for and only intakes air.

Found one, cheers.

I'd only really want one because I reckon it looks pretty cool, but yeah I figured it wouldn't really suit a dive that it isn't tailored for.
What the fuck are they putting in their rebreathers that water is going to murder the diver?
Western ones work for 4 hours (not two), lack the weird air bag around the neck, and make zero mention of the possibility of fire. Also the full face mask is optional.

It doesn't seem to be model specific due to how they work.

That is referencing the fact that the contents of the rebreather is, by its nature, self-oxidizing. I've not seen any evidence that other rebreathers ignite when breached.
EDIT:
Yeah, it is just the Russian stuff. They use this:

Western ones utilize other oxygen mediums.

Counterlung doesn't need to be that much bigger than lung capacity of divers, so an excessive counterlung can instead be replaced with more gas reserves.
