Best bags for a Sawyer Squeeze gravity system?

I know the Smart water bottle is a great way to feed the Squeeze. But I'm thinking about a group gravity fed system. Below are a couple examples of larger bags that work with the Squeeze. But I'm wondering if there are larger, collapsible, reliable, better bags out there for this? And maybe something that is less expensive?

(I don't use water bladders as a drinking device. So using those on the receiving end aren't doable for me.) I'm more interested in a one gallon or larger system that would work on both ends. Something you could set up before dinner or at night to filter your water for the next day. Or at least a good start. And transfering that water into Nalgenes or canteens. A gallon will do 4 Nalgenes. This is also for high mountain water. So I'm not concerned about filtering a lot of muck. I know these get clogged. And you might run into an issue of having to backflush part way thru your gravity feed. Or is that not a concern?

I'm still a little unsure what size cap I'm looking for on these containers. Other than I know it's standard soda bottle size. Is there a technical size for that to search google with?

After some research it looks like the Platypus system below would be the way to go. It's all set up and at 4L and $45 looks like the go so system. But I would prefer it be vetted by you guys.


This looks like an all in one system. That you can just put a Squeeze inbetween? Wondering if the fittings are correct? It's $45. and actually looks like the sweet spot for what I want to do. Although I don't know anything about the reliability of the bags.

Below are 3l bags for about 20 bucks each. That screw directly onto the Squeeze.

Here's the Sawyer one gallon system. But it's almost $70.

And then there's this below. You can convert a dry bag into a dirty water reservoir.

Here's a giant 10l bag for $75. I think the above (if it works - I read about it on Backpackinglite. And it sounded like it worked good.) would be a better option.

an MSR dromedary and one of their hose kits is a simple way to get a gravity bag that is more robust then most on the market. I pick them up pretty regularly from REI garage sales for cheap so I keep one rolled up in each food bag. They also make great training weights in backpacks.

Many reviews on Amazon mention bad taste. I assume you didn't experience that?

I've gotta hit some garage sales again. I found my first Fenix flashlight there. HAve owned several now.

CNOC. The clip on opening makes for fast and easy filling.

I have a couple of the 6L MSR Domedary bags which I like a lot. Not the place to sing their other praises here, but in reference to whether they have a plastic taste or not: They did have a slight plastic taste for the first few fillings, even though I washed them out after first purchasing them, but it eventually went away. I got them several years ago, and I don't know if later batches have changed at all, but it mostly seems to be a first-impression issue.

Please sing their praises. This is most certainly the place to do it.

Haha. Well, I don't have much original to say about them that you couldn't find elsewhere: mainly that they are the toughest non-rigid water container I've ever found, and that they are very compatible with other accessories because of having a Nalgene wide-mouth threaded opening. But I figured this thread was primarily related to whether or not they'd fulfill your use as part of a basecamp-style Sawyer Squeeze system.

I think the Dromedary 6L or 10L size would do just fine for your purpose, and I believe there are a plentitude of adapters for Nalgene wide-mouth to "bottle thread", or you could just in-line a Sawyer MINI with the usual drink tube they come with.

I did get to try the_alias's CNOC (for a beFree) on a recent trip and the top opening was much easier to fill from a tiny stream then most soft bottles (certainly a world better then a platypus) but I still have trouble trusting those soft bottles long term. I had a gen 1 hydrapak that felt like a very similar material that sprung a half dozen pinhole leaks from the slightest whisper of a cactus, one that a platy or dromedary would have laughed at. They mostly self-healed surprisingly enough but it will still weep a bit if squeezed hard enough.

the other disadvantage of a cnoc is there is no hose to build water pressure, of you are squeezing its no matter but if you want to gravity filter I think a few week of hose makes a big difference.

It is on your original list CNOC Outdoors. Combined with HydroBlu Versa filter, they can't be beat.

I would also recommend the MSR dromedary bags as they're legitimately durable (for a water bladder) and there are guys in Australia in the ADV bike world who transport fuel in them across deserts.

On the subject of gravity systems. I ran one for a couple of years as a more base camp style system while backpacking when with friends using a Squeeze and the Platypus Gravity System's dirty and clean bags. The filter clogs very quickly and needs backflushed, so count that into the setup IMO (do not leave out the syringe) and plan for a way to hang your dirty bag several different ways in order to get it done well. I got a couple lightweight carabiners, some paracord, and some shock cord and keep it in the water kit with my gravity system. Your quickest result will have the filter as far away from the source bag as possible, so take that into consideration when setting it up. I had the dirty bag, about 3.5ft of hose before the filter, then about 2ft to the clean bag. Hanging it all vertically was of course the best, but suspending the dirty bag and hose to the filter did just fine. I seemed to get a reduced flow rate after a couple 4L bags in a row. Oh and also the rigging material for the dirty bag can be used to rig it outside of a pack if you want to pack dirty water with you on the trail.

Another factor that can speed up the process is your clean container. By far the fastest way I found was suspending the system with a container to catch the clean water at the end like a nalgene or canteen. This is definitely more audible but works well. I've since switched to the Katadyn Be Free filter for my GHB/BOB because the flow rate is MUCH higher and it's easier to clean in the field, so I don't use the gravity system as a primary but I still have it at home.

I am going to review one.

Thanks. I have been busy with stuff but missed the forums.

I got the CNOC in the mail along with the winter supply of water tabs (burn about 20 of them on the fly each winter). Anyways it's a platy type bag which fits my Sawyer Squeeze nicely. Mini as well. I will post some pics in a day or so. Can't really say much more than that till I get a week of use. It was cheaper to buy direct as got free shipping (4.50 shipping on AMZN).
