I love to hike and camp but hate to carry heavy water. This allows you to purify any water not matter where you are. I love that it has a solar charging case so you don't have to carry batteries around!
If you are some wandering world traveler or on one of those shows where you jump out of planes and land on top of the rare lizard you were looking for, this water purifier is for you. It requires no batteries and can be charged by the sun anywhere. No matter what, you'll always have safe water to drink.
