A side note on water filters.....

I ALWAYS have at least three ways of making water safe to drink:

#1) Pre-filter and boil.
#2) Water purification tablets.
#3) Filter.

The filters I use....

A) AquaMira Frontier (this is a 20 gallon suck through straw type) - for my belt kit.
B) Berkey Sports Bottle (this is a fill the bottle and suck through the straw) - for my GHB (lets me keep extra water on hand while on the move unlike the straw in Item A)
C) Katadyn Hiker or Pocket pump filter - in our BOB's.

This is my Berkey bottle filter...
