I'm sure almost everyone who has made up a psk has tried to figure out a good way of waterstorage. While condoms arent a bad choics they are very fragile. The best thing i have found that works well is the "poly water bag found in m p i outdoors "you can survive" survival kit. The bag holds about a liter and is very compact. with a zipper lock closure it holds up quite well. I found this to be much better than a condom because it is much stronger than a condom and is almost as compact as a condom making it almost perfect for any psk.<br><br> Tom
