Sawyer Squeeze Water Filter Pouch - Replacement Pouches for Sawyer Water Filtration System - Perfect for Camping, Hiking, and Emergency Preparedness

These things saved our group during a weekend hike. All of then had holes in them by the end of the trip because some of the folks twisted the packaging instead of rolling them. If you use them correctly, they should hold up.If you're going to carry water in these squeeze bags, replace the little white cap with a Smartwater cap. This is why 4 stars, not 5.My system:>> Need to think of backpacking in "systems.." Water system, sleep system, kitchen system, etc.My water system:- One 750ml flip top Smartwater in water bottle pocket. (A one ltr. Smartwater is too bulky for my pack)- A second one inside pack, but with screw on cap, not the "flip top" cap that comes with the 750's.- ONE of these 2l squeeze pouches.Method:I drink one 750l at water stops, then filter/refill my main 750. This is the only water I carry unless I'm going several miles w/o water. If more than a few miles, I'll fill my second 750 with unfiltered water. I never carry more than the 1.5l.I ditched the .5l bag that came with the filter. Too small: I don't want to hang out by a brook refilling the water bag, filtering, refilling. For camp, I fill the 2l at some water source, bring to camp, filter for drinking, normally don't filter for boiling. Often 2l + one 750 is enough for a night at camp. Backup: If the 2l bursts, no worries, I can use either 750 to attach the filter. Thus, all water containers fit the filter; no Nalgene "wide mouth", etc. This is just what works for me...So, I've used the 16oz, 32oz, and 64oz for my CDT thru-hike during various stages.I will say to stay far away from the 64oz, as all the three I had all blew-out on me within the first month. The failure occurred at the base/neck of the capping nozzle, where the bag simply burst.The single 16oz I had lasted the whole trip. Though, admittedly, I rarely used it as the volume was simply too little to use for a long thru-hike. I'd recommend it for a day hike where water is fairly plentiful.The 32oz is where its at. After the failure of the three 64oz in the first month, I purchased and used the 32oz bags for the remaining 4-1/2 months and never had a single issue. At times, I even forwent water bottles, and simply utilized these to carry water for prolonged periods (such as the Great Basin in S. Wyoming. Yuck!).P.s. Keep in mind, your Sawyer filter should be backwashed fairly often, else you'll be putting more pressure on these bags trying to squeeze the water through, thereby increasing the odds of a premature bag failure.Hope this helps!If you're seasoned backcountry person, just read my last update. If you're going backpacking for first time and unsure if you'll like it, continue reading.Anyone going into the backcountry depends on their gear. The ability to filter water is a big deal. I have owned two sawyer mini filters for my family of four for four years. I expect we've carried them 300 miles and one of the bladders recently broke. Estimate 2l ever 10 miles--so approx 60l of water. The original were quart size so that adds up to 120 uses. Only one has failed and it's due to my inexperienced brother in law who wadded it up instead of folding like toothpaste... So I replaced it with a 1L size bag (it was way cheaper for some reason and added negligible weight). On my first trip of 40 miles it failed on my last day! My filter was flowing fine... rolled it up like toothpaste and it blow out at the neck. Bummer! Had to use a 2nd bottle as my bladder. Luckily conditions were nice otherwise it could have been a big invconvenience. Anyway... Maybe it's the 1L size, or that they've gotten cheaper, or I just got a bad one. Don't know, but thought I'd share. Disappointed. Take care! See you out there!Update:Junk... Downgrading from 3 to 1 star. Pretty sure all three of the liter size bladders failed at the neck. I believe I'm speaking for all of us backcountry junkies that we have no time for gear failure. Since I have another trip in a month, I'll be researching alternatives. I'm going to research using a Smart water bottle as my bladder--I actually did this on my last trip with success... but need to improve some things. With minimal searching, you'll find documentation on doing this. I hope this saves me, and others, inconvenience, frustration, money... and reduces chance of drinking contaminated water. See you on the trail!Another udpate...I realize everyone is on a different budget. And the 'durable/lightweight/low cost' triangle triangle (apply any two, sacrifice the third) applies to all our gear. But something I wish I had found sooner, was the CNOC bag:https://www.amazon.com/Cnoc-Outdoors-Container-Thread-Orange/dp/B07QBQ894L/ref=sr_1_1?crid=32AKB3F9SUR9Q&keywords=cnoc+bag&qid=1653421729&sprefix=cnoc+ba%2Caps%2C85&sr=8-1Pair CNOC with a sawyer squeeze with threads:https://www.amazon.com/gp/product/B00B1OSU4W/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1And a threaded coupler:https://www.amazon.com/gp/product/B018NJC1A6/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1Then stick with the 1L Smart water bottle that attaches to the threaded coupler on filter outlet. Leave the threads loose to allow air out when filtered water goes in. (I always carry three of these on my trips). No link for these :)A little practice and the cnoc will fill in 3 seconds. Attach the filter and Smart bottle, and be able to stand or sit comfortably to filter your water... Way less fumbling. Cnoc allows for heavy squeezing, but the filter also has better throughput so squeeze less! All of this saves time! At camp, string it up easily to something and let gravity do the work.Yes--it's more expensive... The value triangle doesn't mention time and/or convenience, but this needs considered. With the CNOC competition being these now crappy saywer bags, it's worth the splurge. On my last trip, two of the guys I was with ended up using my system (yeah I know... some would never take this risk), but they were very appreciative and now use the same system. This wasn't my idea--found it on that major video repository everyone knows about. Take care! See you on the trail!Generally very happy with these "own brand" Sawyer collapsible bottles, but a couple of points worth noting: -1) Some reviewers suggest that Sawyer’s collapsible water bags are very difficult to fill, unless there is a strong flow of water. The simple way to ensure that the bottle fills easily, regardless of whether there is strong water flow or not, is to “inflate” the bottle before presenting it to the water supply - by blowing into it as if you were blowing up a balloon.Of course this advice comes with the caveat that your mouth will come into contact with the bottle’s outlet, which may carry contamination from previous fillings with unfiltered water. Only the user in the particular circumstance involved can decide whether there might be any riskinvolved.2) It has been suggested that the threads of the Sawyer filter are the same as those of other makes of collapsible bottle such as Platypus,and of various plastic drink bottles.I cannot comment on the use of plastic drink bottles, but I can say definitively, that the threads of Platypus collapsible bottles are NOT exactly the same as those of the Sawyer Mini.Although a Platypus will actually screw onto the Sawyer, it will only do so with a very slight “cross threading”. In the case of the Platypus bottles I’ve tried, this resulted in a slight seepage of water from around the unfiltered “neck” side of the Sawyer. Meaning that unfiltered watercould easily end up in whatever filtered water container was being used at the time. The seepage increases when squeezing the Platypus in order to speed up liquid flow through the filter.Personally I’ve not had any real problems in using Sawyer’s own bottles, although I find the 32oz. is much to be preferred over the 16oz.The one small gripe I do have, and the distinct advantage a Platypus bottle would have, (assuming a perfect connection to the Sawyer could be made), is that the Platypus range includes a fully transparent bottle, so its content can be seen and inspected for any obvious debris or other matter. It also makes it easy to see whether the inside of the bottle has been properly cleaned and dried before long term storage.I've gone through about 5 of these now, including the original smaller bag included with the filter. They all burst after approximately 2l pushed through the filter. Knowing this, I am quite careful and only use about half squeezing force with my hands only (and Im not a strong guy) which is painfully slow to filter. Furthermore, when it bursts, it sprays where the filter points, so into your filtered water. Do not expect one bag to last you even one trip, if you buy this, always carry a spare or 2.After the bag bursts, it is still possible to push water through it by holding around the neck to minimize leakage. The leak will increase as you filter, so you're on a timer. After the burst you can filter at somewhere between the ratios of 3/4 or 1/2 (water coming through filter vs water being lost to leak).This is also a lot more strenuous as only one hand does the squeezing and the other has to continuously hold the leaky area in a tight grip.This product is criminally bad considering its purpose.The Micro Squeeze has got to be one of the best or the best system of its type available. The bags themselves have had one or two reviews of them splitting, but mine haven't yet and work fine. I always carry a spare, but you can always use a normal plastic bottle, although that defeats the compactness aspect?Being bags they are a little more awkward to fill as immersion compresses the bags. A tip is to blow into them and immerse horizontally; then they fill ok.Replacement bags are not easy to get in the UK and limited in sizes available. Nor are they particularly cheap.The filter bodies themselves are amazingly compact and light and work very well and reliably and are easy to clean after use/trip. All packs very small and light.The 64oz supplied have both failed, one split the other delaminated having only being used 6 days in total. I have had no problem with the smaller sizes, their construction is quite different. I feel that I have been sold the older style, which is reported to fail.Having asked if this is the case, I have not received any replies from sellerThe bag that came with my Sawyer filter split after 1 use on a wild camping trip in the Welsh Brecons. I went for a 3 day wild cam this weekend and took 2 of these liter bags. Both of them split this weekend. All 3 bags split at the same place which is where the neck is sealed to the bag.I thought I was perhaps being too hard with the first bag and I made sure to treat the new ones as gently as possible.Please do not use these for wild camping or for multi day trips without also taking a stove or something as back up.
