So, was looking at a larger water carry solution... some larger than a CNOC bag etc, but not something super heavy like those 5 gal foldable/crushable water bladders you see at walmart and such.

Would also be swell if I could connect a filter such as Sawyer Squeeze up to it, even if with an adapter of some sort.

I see several 1.3 / 2.6 gal plastic water carry "sacks" on Amazon and the like, which might fit the bill, but not able to determine thread sizing on them.

Any suggestions? Doesn't have to be UL I suppose, but looking for something reasonably light to bring water back from a distant water source and just have in camp for small group or multi day stays, etc. Mabye something like the Platypus Water Tank or maybe the DromLite bags, although I don't think they are available anymore...
