Any thoughts as to their application as a PSK container?

It's been a while since anyone has posted on this thread. How are those aqua pouches working out?

I've continued to use them on hikes to treat & store water. They are still doing well.

Thanks to Glock-A-Roo for the update - and to Hikin_Jim who thought to ask.

Cool. I've been thinking about getting some. I've got a Nalgene 3L self standing water bag in several of my kits, but the Nalgenes with there 2 or 3 inch hard capped openings don't pack at all well for PSK use. The Aqua Pouch appears to be vastly superior to a condom.

Interesting to see how the topic twists and turns throughout a thread; Thanks for all the info guys, I will see if I can source this or a similar product in Oz.
