Glen B.wrote a review of MSR SweetWater Purifier System on September 14, 2012
Just got back from Denver. Used the purifier on two overnights and it worked great. Saved hauling water which helped keep the backpack weight down. 2 people it is easier but one can do it just fine.Didn't use the sweetwater. From other reviews didn't see the need. Save yourself from carrying all that extra weight!
