For you guys and/or gals that like to filter your water while affield, I saw they make a new filteration straw, its really small. looks to be about 6-8 inches or so long, and thats it, with a built in filter, they say it last only 12 months and it can filter a certain amount of liters. Not sure who makes it, but on the straw it is printed, "Water is Life". they are said to cost $10.00
I just saw that they are sending thousands and thousands of them to Haiti, due to the contamination of their water supply.
