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