Collapsible Water Container, Freezable, BPA Free Plastic Water Carrier Tank, Outdoor Folding Water Bag for Sport Camping Riding Mountaineer, Food Grade

Both products function as described without leaks (HOWEVER I did NOT go so far as to sit on them, so can't vouch for that!) and appear sturdy enough to last quite awhile. I have no idea, as it is not readily apparent, what the seller is talking about in terms of the aluminum foil lining, and I must also add that I have not as of yet attempted to use the freeze feature. I did test the hanging feature of the 5L by cutting out one of the holes (must be cut out, will not simply open if pressed with fingers) and placing a carabiner through it, and it held fine, though I have not yet hung it for an extended period. An additional feature not mentioned is that the bottoms are designed so that the bags stand up when full, though this works better with the 5L than the 10L, which has a tendency to fall over easier; but since this isn't even listed in the description, i have chosen not to deduct a star based on this. Will update as necessary if bag proves defective, including if freezing feature creates problems.

Used these to make large blocks of distilled water into ice for the camping coolers, and they really work a treat. No fun tastes once the water does melt down, and no sloppy, sloshy coolers full of ice melt.

Super lightweight, durable, holds water! Taken on a couple of pretty intense camping trips, they've been smashed around and the still work fine and pack up like nothing. Buy them.

These are everything as described and I look forward to using them. I plan to freeze them for the cooler and then use one for water. If need be I can write an after use review but they are what they say they are. Not flimsy which was a fear.

Used this for my backpacking trip in Havasupai Falls in Arizona and I’m so glad I saw someone recommend these!! It was only 2 of us for this trip so we only used the bigger one to carry our water to our campsite. Super convenient so that we didn’t have to go back and forth to the water spring. Also folds flat and super easy to pack away in our backpack.Will probably use this for camping trips so we can avoid having to constantly buy plastic water gallons from the store.

So far so good! We have used these on 3 backpacking trips with the Venturing Crew. They are so much easier to pack, and don't take up all the room in your pack.

Used these for water storage, living out of a van and not being a careful person I have dropped these into various places including but certainly not limited to rocks, sticks, pine needles,and pointy rocks. The bags have all held up incredibly even when dropped from a couple feet onto what would seem like unforgiving ground.They hold water excellently, and one of those bags ended up being used for gasoline on a motorcycle trip and then for an extended period of time thereafter. The water bags are showing scratches and wear but no leaks and seem solid still.After probably a couple months with gasoline inside the one bag had accumulated what looks like little bubbles filled with liquid all over. It hasn’t leaked and I continue to use it as so. Though I worry that’s compromising some of the integrity.I can happily say that in over six months of use these have held up well and do their job!Works much better for water I think than gas but still!

Easy to fill, bag stands up as you pour into it, seals up well, feels durable. Freezing water worked well and helped keep our cooler cold during 4th of July. I really like that when its empty they take up almost no space. We will probably keep these full and frozen with drinking water in our freezer and pull them out when we want a chunk of ice in a cooler. Worked good camping when the ice melted we drank the water.
