I can see that some might say that this isn't their deal, but for a group water filter it's pdg. A 5gal bucket you can get for a couple of bucks (or maybe already have), a few minutes setup and you have a robust water filter that can outlast you. It can also be used to haul gear to and from the area. Maybe it's not a UL kit for an individual, but I use mine for as a group water filter. Great not having to worry about grandkids or scouts damaging a soft bladder.
