SteriPEN Sidewinder Purifier Blasts Dirty Water With UV Rays

Fresh from this year's Outdoor Retailer expo comes SteriPEN's new Sidewinder portable water purifier. You can leave the batteries at home on your next trip, as the Sidewinder only needs a good cranking to power its germ-killing UV bulb.

The purifier can take a liter's worth of water at a time, and will alert you with a green LED once you can stop cranking and start quenching yourself, pathogen-free. Look for the Sidewinder to hit shelves in September for $99.95. [Gear Junkie]
