WaterWear Backpack response

From reading the article posted to the course Google Site, it sounds like the WaterWear backpack was developed by people at companies, as a safer and easier way to carry water. It seems like a pretty simple idea - to have a backpack filled with water.

Some pros:

-Keeps water away from the ground (no encounters with puddles/dirt)

-New materials: not a used oil/chemical container

-Seems easier than carrying water on top of your head

-Hands-free

Some cons/questions:

-Only holds a small volume of water

-How do you clean this?

-Is it expensive to buy/produce?

-Does it break/tear easily?

If I had $10,000 to spend, I would maybe spend some money on distributing this, but not all. If I had that kind of money, I would spend a major portion working to create infrastructure and a safer and more accessible water system, so that the water source would be closer to where people live. Making the water more easily accessible would remove the need for women and girls to make day-long trips to water; instead, they could make shorter trips to the well.
