The latest advance in water purification technology!

The smallest, lightest SteriPEN®, the Adventurer Opti, uses a revolutionary optical eye to sense the water. The patent-pending technology provides safe use and the standard insulating sleeve around the UV lamp allows purification in even the coldest of waters.

Fast, Light, Easy and Effective, the Adventurer Opti provides the ultimate protection from waterborne illnesses. Giardia, cryptosporidium, bacteria and viruses are all destroyed –in seconds—by SteriPEN® UV light. Similar to other SteriPEN models, the Opti purifies 0.5 L (16 oz.) in 48 seconds and 1.0L (32 oz.) in just 90 seconds. The UV lamp provides up to 8,000 one-liter treatments.

The new optical sensor doubles as a convenient LED flashlight. It’s 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. The clear lamp cover focuses the LED light.

The Adventurer Opti retail package includes 2 non-rechargeable (disposable) CR123 batteries and a neoprene case with belt loop. Device works with containers with minimum 1.75 in. diameter opening (ie Nalgene wide-mouth bottles).
