Grayl Ultralight Compact Water Purifier

The Grayl Ultralight compact purifier bottle is the easiest, most practical water filtration device I have ever come across. I have used it everywhere from the remote wilderness in Utah to hotel sinks in Mexico, and even once at a boat rinse-off station in Hawaii; it has never let me down. It is ideal for backpackers, day hikers, and those traveling to new cities.
