The SteriPen Adventurer Opti is their smallest and lightest SteriPen, using a revolutionary optical eye to sense the water. This patent-pending technology ensures safe use and provides purification in even the coldest of waters. The new optical sensor doubles as a convenient LED flashlight, which makes it a great backup light when camping or taking a night-time walk to refill your water bottle. The Flashlight mode is activated by pressing and holding the single button down for 3 seconds, and the clear lamp cover focuses the LED light. Works with containers with minimum 1.75" diameter opening, such as Nalgene wide-mouth bottles.
