Spent $180 on a water filter for the Sierra loop and never opened it once
I carried that thing for 6 days on the Rae Lakes loop last August and every stream I crossed was already clean and cold, so I drank straight from my bottle the whole time. Now it sits in my gear bin while a $4 bottle of Aquamira tabs does the same job at a fraction of the weight. What gear did you haul around for a whole trip before admitting you never needed it?
