When you're backpacking, space is at a premium — The BOttlelight saves space by merging two essential must-haves: a portable UV water purifier with a camping light. In just 60 seconds, UV LEDs eliminate 99.9% of bacteria in 1 liter of water. A 45° reflector at the bottom provides simple and glare-free light source at night. The unscrew able bottom makes it easy to clean and the build in carabineer clasp on the top provides endless possibilities of attachment. Constructed from durable pressure formed aluminum parts and shatter proof glass, it will live through many adventures.
