The Platypus Collapsible Water Bottle

Clean water storage containers are going to be in serious demand if the SHTF, both by you and all of the sheeple too. water bottle for survivalYou really can’t have enough, but at the same time you don’t want to waste room in your gear bag on more water bottles when you’ve already filled as many as you can carry. Enter The Platypus Collapsible Water Bottle.

From the Cascade Designs company website:

  • 100% BPA free
  • Compared to a hard bottle of equal volume, they weigh 80% less and take up a mere one fifth of the space when empty.

There’s really not a lot to it: A heavy duty plastic bag with a drinking spout. However, when they say heavy duty they mean heavy duty.

Quick Navigation


1. Obviously it is great as a very small and light backup water container.

2. According to the company you can put boiling water in the platypus and it will be fine. Since it’s BPA free there’s no danger of contamination either.

3. One reviewer on amazon suggests filling it with hot/boiling water to use as a hot water bottle in bed. This could be potentially useful in a cold survival situation.

4. You can freeze it. I don’t know how or why you would ever do this in a survival scenario, but at least you know it will stand up to winter conditions.

The Platypus seems like another one of those good things that is cheap, handy, light, and small that you can throw in your Bug Out Bag or Urban Survival Kit and never regret.

A word of advice: The laws of physics still apply, so don’t fill it completely full like a balloon and then expect it not to pop when squished. Fill 90% so that it is flexible and strong.

The new version of the 1 Liter Platypus Collapsible Water Bottle goes for $12.95 on Forge Survival Supply. (It has more than 40 positive reviews.) The Platypus also comes in a 2 liter version, when 1 liter just won’t due.

  1. I love the platypus water bags. When I bought mine I stood there trying to decide what size to buy. The store manager was nice enough to tell me, "take em out of the pack and look em over" (it was a small outdoors store where you still get personal service.) Anyway, since all of them were virtually weightless, I opted for the 4L water tanker. If I don't need as much, I just don't fill it up all the way. I do prefer to have the option to carry more if I want. Either way 1L or 4L, I still got it covered. I've heard that you can take the bags out of those "box-o-wine" containers, but I cant comment on durability since I have never tried it. Besides, we all know that the finest wine comes from a bottle with a twist off cap… not a box, LOL.

  2. Funny story about freezing water bottles . I grew up and lived most my life in Arizona , then moved to Maine . Needless to say , all the subtle things you dont do in winter there did not occur to me . I bought a case of bottled water to take home after work and put it in the cab of my truck . I was running late so some other things were in there as well . When I opened my truck up to go home , the whole case was froze up and split open as well as a new package of gel pens and some snacks . I stopped leaving things in my truck . Good point the article made about winter bug outs .

  3. I love the platypus bags. Too bad I only have 1 though. I have a few nalgene bottles though, and a million surplus army canteens. Although they take up more space, the canteens come with a metal cup that fits on the bottom that is really useful. Overall, I choose platypus though. =)

  4. I just picked up one of these from the store the other day and i've been impressed. I haven't used it a lot yet but I can really see that it would be useful. I really recommend that everybody buys al least one

  5. Wondering about a reason to freeze water bottles? I keep them in the freezer since I live in California and deal with power outages from simple things from earthquakes, storms to drunk drivers hitting taking out the transformers. When the power goes out it works like ice packs in a cooler. When the power goes out I place them around the milk, cheese and other perishables in the fridge and the remainder in the freezer.

    In the event of something serious it keeps things cold a bit longer so you don’t have to worry about eating it all in the first 24 hours or throwing it away.

  6. I’m using a Eberlestock hunting pack for my BoB , Got rid of my Badlands in favor of that one for several reasons , one being they are designed to be heavily customized , They offer a great heavy duty 2 and 3 liter hydration bottles for their packs like the one above , I got it and tested it out on a trip . Very useful to have as mentioned above , And one less thing to worry about when its filled . I used the built in one as a reserve when the other water I carried in ran out . Nice out of site , out of mind backup .

  7. The two liter bottle fits pretty well in a 2 qt. Ranger canteer cover. What is nice about that system is that the ranger cover fits nicely onto all of my ALICE gear. It gets a little smooshed up, but I never carry it full anyway. I also carry two 3 gallon heavy bags with spigots. I used to carry 5 gallon bags. But my kids were younger and had a hard time carrying the big bags when I sent them to get water when we went out survival camping. Most of my BOB gear is just camping items that I use a couple of times a year anyway. Ziploc bags also make decent water bladders for camp use, but don’t try to transport them when full, you will just get a puddle in your pack. Thanks for reading my ramblings.

  8. I have been using mine for the last 10 years and I love them. Living in the desert I do freeze them before going out and then drink as it thaws, it helps me keep a lot cooler that way. Of the 10 or so bottles that I own 2 started to leak at the seams. I sent them back and the company replaced both for free.

  9. I have really liked my Platypus bottles as well. I got mine from Academy Sports, the .50 liter is $7.99 and the 1 liter is $8.99, needless to say I bought 1 liter bottles.

  10. What a commendable work you have done, with simplest of language. I can’t resist myself to leave a comment and trust me it’s hard to impress me.

  11. I prefer hard/semi-hard military canteens, a 1quart with canteen cup, stove, and cover which attaches to my belt so storage space not an issue and they're very tough. Also, usually 1-2 2-quart canteens with cover(s) which have shoulder slings. I also carry 4-5 gallon-size ziplock bags (very cheap), primarily to gather and carry untreated water. the clear plastic bags can be set in the sun to use UV radiation as partial treatment and to let dirt, etc. to settle to the bottom before carefully pouring into canteen cup to boil. That way only potable water ever goes into your canteens! Of course, untreated water can be used for washing (don't ingest or let into eye sockets), and other things. The zip-lock bags can be opened to use as solar still(s) or to carry food items or any small items that you want to keep dry like socks!
