Description
Features
- You’re leading a field camp this summer and the last thing you want to do is take care of a bunch of college kids with giardia. You have the GravityWorks filtration system, but could do with a bit more capacity, so you’ve grabbed the Platypus GravityWorks 4.0L Replacement Reservoir Kit. Your previous dirty reservoir was getting a bit grungy, so you get to start over with a brand-spanking-new bag, and now you can store an additional four liters of fresh clean waters for your thirsty undergrads. While this kit does not include the actual filter and filtration tube, these replacement reservoirs come in handy when you need additional capacity or a couple backups—just in case.

Large size, can filter a lot of water. No complaints. I have several sizes of bags that I take, depending on the type of camping I am doing.

These are my preferred water containers given price/weight/usability/durability trade offs. Pros: light and compact, works with Sawyer filters Cons: The way the bag hangs on the strap causes the ziploc like top closer to want to come open. I will probably 3D print a bracket that is light and holds the bag properly. The Platypus bags and bottles are hard to dry. My Camelback dries in 6 hrs. These took longer.

Bought this product to use on a series of 3-4 day backpacking trips climbing 14ers in Colorado. It was the perfect solution for our large family (7). We also bought an extra 8L set of bags to pair with the 6L set reviewed here. Our primary water sources were high alpine lakes and streams but occasionally we would need to use it at water sources around 8k in elevation. Generally, the sources were clear. The water passes through the filter quite efficiently and the stated 1.5L/minute seems accurate for our experience. We only used the “clean” bags on our first trip after which we ditched them and just filled our respective water bottles directly from the hose. Having two “sets” of bags ensured that no one ever had to wait for water.

I use this as a dirty water bag with a DIY gravity filter based on a Sawyer mini and I LOVE it. I did replace the strap/buckle with 1.8mm Reflect It cord with a brummel loop splice and a dutch hook to reduce the bulk and because the strap seemed to hold water when wet. The wide mouth opening makes scooping up water from a shallow source really easy and the placement of the outflow means you can easily get most or all of the water out, easier than a bladder that has the outflow located on the front face (like most CamelBak bladders do). Platypus does make a 4L version of this but it's unnecessarily large and bulky. Normally I don't need more than 2L of water at a time and if I do I'd rather just fill up the dirty bag twice

This bag is the sorta soft and "stretchy" material found in the PlusBottle. Much better than the "krinkly" stuff Platy makes the regular 2liter soft bottles out of. I use it as a squeeze bag for the Sawyer Mini (or gravity-feed for same when I have time). Works great, as the zip closure allows the bottle to be filled in one dip, and hasn't come open despite much squeezing. I had to buy a male CPC fitting (search AZ for "Katadyn Quick Fill Adaptor") and re-purpose some hose, but now I can dip the bag, do some hookups, walk away, and come back to a filled 2l clean bottle. I have filtered about 20l using this system so far. FYI- Sawyer uses industry standard threads which match water and soda bottles, whereas Platypus uses proprietary threads on their Soft- and Plus-bottles (to lock you into buying their caps etc). That's why I bought this bag and connectorized it to feed the Sawyer: the 2l SoftBottle wouldn't seal against the standardized threads on Sawyer filters.
