The Katadyn Hiker Pro Water Filter has the improvement of a second filter that wraps around the internal filter cartridge making the cartridge last longer. Great reviews on this hiking filter. Great choice for a long term camping trip or thru-hiking the triple crown.
This is the model water filter I personally carry in my backpack.
The Katadyn Combi – Water Filter For Hiking. The Combi is a state of the art water filter that is a must have for the lightweight hiker. Keep this at the ready in your bug out bag or backpack. This is a top rate hiking water filter. I would buy this water filter, If I didn’t already have the MSR SweetWater.
Top of the line water filter for hiking can fit in your pocket. Remove harmful microorganisms from the water you find in the woods. No sense spending your time camping laying in your tent because you drank contaminated water.
