Want to make sure that you have clean drinking water at all times, without having to carry around a bunch of brand name water? Then you'll want to get your hands on one of these 'All Clear' water bottles by Camelbak. Here's how it works:

The LCD screen on the cap pretty much walks you through it. It counts down the 60 seconds it takes to purify the water and includes information about your battery life. The only thing you have to do is swish the water around while the bulb zaps your water to ensure all the water is treated and you are good to go. The UV bulb is supposed to kill the bulk of all bacteria, viruses and protozoa -- in fact all but .01 percent of each type of intestinal nightmare per 25 ounces of water, according to stats released by the company.

The UV bulb is projected to last for 10,000 cycles that should clean approximately 101 ounces of water a day for seven years. Plus, the battery is rechargeable.

This bottle is a must have for the adventurer who doesn't want to get caught with their pants down, or anyone who wants to make sure their water isn't full of nasty little critters.
