The Sidewinder features an exclusive UV system that destroys waterborne bacteria, viruses and protozoa such as giardia and cryptosporidium. Its hand-powered system is as efficient as it is effective: just 90 seconds to purify one liter of water.

The Sidewinder purification system includes a SteriPEN Pre-Filter for use prior to treatment if the water contains particulates, as well as a one-liter Tritan BPA-free bottle.

The battery-free Sidewinder is extremely packable and portable. Plus, with no parts to replace or filters to clean, the Sidewinder is always ready to go. It’s economical too: the Sidewinder purifies 8,000 liters at less than 2 cents per liter, about 5 cents per gallon.
