>>2836358My comment was made in a specific context and I stand by what I said.
At the low need end,the weight of rucking in water isn't a real issue. you must carry a given quantity of potable water anyway so the amount you can actually avoid carrying is fractional, you piss the water out as soon as you start, you can dump surplus towards the end.
As you get into the high needs bracket, such as the example you present, where you couldn't carry sufficient water if you wanted to, at that point I would still recommend against the filter but on a different basis. The scalability, survivability, liability presented by the filter system makes it a poor choice for those managing critical water resources.
you obvious do just fine with the filter, lots of people do, there's no fundamental issue with filter system. but that's no reason to recommend them, and I don't.
