As the other user said, I found them from backpacking for roughly the same reasons.
Subsequently I’ve found them to be extremely convenient whenever I travel. They fit into a vehicle cup holder, will last months with daily use, and are cheap enough that I don’t care much if I lose or abandon them. If I’m flying I can buy them at the destination. They’re lightweight, durable, disposable, and easily replacable across the US.
At home, regular life, I avoid the cost and waste with Nalgene & stainless steel. My oldest Nalgene is thirty years old, my oldest stainless steel a third generation hand-me-down that’s eighty years old. This is the way.
I use two of them for backpacking. The Sawyer (and a number of other) water filters screw onto standard threads, so I can use 1L potable and 1L non-potable when I’m on shorter trips and not using my gravity bag.
In what ways is it useful?
