When you hike, you thirst. If your me you sweat like crazy too, but your milage may vary.
Best way to save weight and stay hydrated is to bring a filtration device. I picked the Sawer 3 in 1 because I like options. Not only does it screw onto a soda style bottle, but it fits inline with my hydration bladder as well. Oh yeah, and as the title suggests, you can drink right from a body of water.
I currently have a Platypus 3 liter low profile bladder. Water gets heavy in a water bladder. . . really heavy. The Sawer comes with everthing you need to start an adventure including a straw (which I’ve never used). Rated for 100000 gallons of water, I’ll all be toasting my good health for many years to come. At just 2 oz (2.6 for me with my hydration lead hose that’s pictured) and .1 microns absolute it the only filtration I pack.
Since purchasing my filter it has joined me on every successive hike and outing. It’s rugged and versitile as well as offering a wide selection of color options. I have been slowly lowering my hydration carry weight and upping my reliance on local water sources to save weight. I have recommended the Sawer to everyone who inquires about emergency or outdoor filtration. Two thumbs up for the sawyer, if I were to adopt a thumb rating system.
