Does anyone have any experience/reviews for backcountry water filters? We are heading out to Colorado this fall for an elk hunting trip and are planning on backpacking in and camping. I don't want to be bringing in any more water weight than I have to, to start with. I want the weight to be no more than a pound if possible and as small as possible, but still able to work efficiently to fill a couple water bladders when needed. I have my options narrowed down to four filters.
MSR Hyperflow, MSR Sweetwater, Katadyn vario, or Katadyn Hiker Pro.
Any thoughts about water filters?
