Water purification chemicals

Agreed. I just experienced my first bout with giardia over the last week and it is truly miserable (and thankfully, I wasn't in the woods when it happened). 2 days of intermittent diarrhea, then it became round the clock (about every 45 minutes, leading to severe dehydration), splitting headache, hot and cold sweats, severe muscle fatigue, abdominal cramping, etc. Not an experience I ever want to repeat.

My $0.02: Use Aqua Mira for in-camp and overnight water treatment for dinner and breakfast and next morning on trail; use either a Sawyer Squeeze or SteriPen for quick on-trail treatment right at a water source to camel up and carry less water as you hike. I've done this for years and it works well, is light, and gives you a backup method in case of loss or failure of one of the methods.
