Lexan flip cap protects spout from contaminants. Semi-transparent bottle lets you see how much water remains. Nalgene ATB bottle fits bicycle water bottle cages. Miraguard suppresses the growth of bacteria, algae, fungus, mold, and mildew in the filter between outings. Replacement filter is available.
Filter is not attached to the bottle cap, making it easy to accidentally splash unfiltered water on the top of the filter when inserting it after a refill and contaminating output. Water leaks down sides unless bottle cap is tightly sealed and is very difficult to squeeze through filter.
