The (almost) always Safe Water Supply
By Anonymous
Lightweight, easy to use, and safe. In many countries, bottled water is water from someone's tap, lake, etc in reused bottles. This solves that practice. Only problem is if you have no water in the area.

This proved very handy while traveling in a country (Ecuador) where the tap water is not potable. It's easy to fill, easy to use. Only problem I encountered was when the bottle had been squeezed when the tip was in the off position -- when opening it, water tended to spurt out. But it wasn't a big problem.
