Would something like this work for the exit bag?

I'm wondering if I can just use a clear drawstring bag. Otherwise I'll just stick to the full face scuba mask.

That looks like it has a rope for the draw string. I don't think I would consider that reliable as the rope could loosen. All it takes is one small air leak to fuck up your plan.

It looks like it has grommets in the corners for the drawstring, so I suspect it would not work.

Remember also that the flexibility of the drawcord on an eb --specifically, that it is elastic-- is important. The seal needs to be dynamic: it needs to be snug enough to keep most of the gas in, but flexible enough to allow the continuing flow of gas to push past it and carry away the CO2 you exhale. A non-flexible drawcord --cordage, duct tape, etc.-- does not allow that dynamic seal.

I should buy that bag to huff stuff in. I don't get high off it, but I like to huff markers and household cleaners. They just smell so good they really make life almost worth it.

Damn, I'm not buying that bag now.
