For outdoorsy people who hate bothering with packs of environmentally-unfriendly plastic water bottles, we’ve got a great alternative that’s sure to quench your thirst. Recently debuted at this year’s Outdoor Retailer Expo, SteriPEN’s new Sidewinder portable water purifier is an ingenious product that utilizes a crank-powered bacteria-killing UV light to create a full liter of perfectly potable water. Simple, practical, and potentially a way to build some arm muscles, look for the Sidewinder to hit shelves this September.
