I have reduced the weight of my pack from 37 pounds down to 22 pounds, and, as part of that, I am going stoveless. For my water system, I am thinking about going with a Gatorade bottle and life straw, but I am wondering if any of you have any experience with the life straw as your main water filter. I also have both a Sawyer and a Sawyer Mini, but the main reason I want to go with the life straw, besides weight, is ease of back flush. With a Sawyer, I will have to have clean water to back flush, and hence the idea of going with the life straw solution, which back flushes just by blowing through it. Anyone have helpful experience/suggestions?
