The Adventurer is a lighter and smaller version of the Classic water purification system, and less weight is always a good thing.  This system is easier than pumping, much quicker than chemicals, and as easy as pulling off the SteriPen's cap and swirling it in clear water for about two minutes.  The UV light renders viruses and bacteria ineffectual, protecting you from E. coli, salmonella, bird flu, typhoid, diarrhea, hepatitis, giardia and cryptosporidium, just to name a few. 

This water purification system means you can go more places, try new things, and be more impulsive, all without the bowel-wrenching repercussions travelers and adventurers are so familiar with.  Protect yourself and enjoy yourself at the same time with a system that is fast, easy, effective, and cost-efficient.  It has been tested by thru-hikers on the Appalachian Trail, Everest climbers, and countless travelers, as well as three different universities, all with stellar results.  Best of all, faithfully using this system means you will never again have to grimly endure jokes about Montezuma’s Revenge.
