Anywhere and anytime! - Grayl Ultralight Purifier Bottle

Been great to use! The extra filter advertised was the one that just comes with it. So really it is just one full unit. But I have taken this and used it extensively in Mexico, many downtown cities, Canada, and the Philippines. Used in streams, lakes, and fountains(not a proud moment being seen scooping water out of a fountain) Easy to use, assemble, field clean, and most of all I trust it!
