If you travel only to developed countries and stay only at posh hotels, that’s cool. Wuss. But if you are like me and occasionally like to rough it, the most important thing is clean drinkable water.
SteriPEN Sidewinder requires no batteries, only your muscle power. Crank that handle until a green LED signals that you’ve purified 1 liter of water.
This item reminds me that I am due for another hike. See you on the trails!
