I was making a list for an upcoming trip. I have a dozen or more water bottles, but they are either heavy (Nalgene 32 ounce capacity weighs about 6 ounces) or have are light but have narrow mouth (Old Gatorade Aid bottles are only two ounces for the quart size). My dilemma is that I like to filter my water through a coffee filter and I need a wide mouth bottle to do that efficiently. By the bye, I know the coffee filters only filter to about 20 microns but I haven't died (yet). I know the size of a giardia cyst is approximately 8 to 14 so they probably are laughing as they swim through my filter.
Pisses of the big bugs anyway.
