Here is one I have been playing with recently as a compact water bottle.
I work at a medical equipment company and recently had to get rid of some rebreather oxygen masks. This particular style has a fairly heavy plastic bag that will hold about 12 ounces.
It might be good for alternative to the condom in a psk as it is more durable. The ones I have been checking out are made by Salter Labs.
If you know some who works in hospital or durable medical equipment supplier ask them about getting you a couple. The added bonus is tha you can always use the tubing for something else.
