I, too, prefer the 1.2 liter size with the spout off to one side, for the same reason. I use them a lot when traveling, to put up some water to have on a plane or train, whereas for other activities I would use my Nalgene bottles and Camelbak. The Platypus bags work great, and spare me from trying to hunt up the military bags when someone needs a kit. For that use, they are preferable to the 1 pint water receptacle bag of the SRU-31/p kit on capacity alone, I think they are more durable, and they are as easily packable. The vinyl 3 pint and 5 quart military drinking water storage bags are great items, but bulky for a small kit. I do worry about the Platy bags cracking, but used for an emergency, I think they will be fine. I pack them flat. The only untoward experience I have had with them was this: my sister and brother-in-law had one either melt or partially burn (I don't recall) inside a duffle bag in the hold of a plane in Russia. Don't know why. Everything else was okay. I have been using Camelbaks for a long time (I cycle) and swear by them for all sort of activities. I have two Camelbaks and a Pakteen. Great invention. The mil bags have a large opening that can be useful for collecting water. The old original jungle canteens had a very good vinyl bladder, but I had trouble with the caps not sealing; the knockoffs have a better cap and a poorer bladder.<br><br>
