The next time you go for that camping trip in an unknown/unexplored region, you must carry this useful gadget. In survival situations, there are few things more precious than clean water — which is why the Camelbak All Clear UV Purifying Water Bottle ($75) is a good thing to have in your bag. It features a UV purification system built right into the bottle that effectively neutralizes microbiological contaminants in just 60 seconds, and can treat up to 16 gallons per charge, including the ability to remove chlorine from drinking water. It even sports a built-in LCD to verify when your aqua is ready to drink.
