Backpacking Must Have

  • Familiarity: I've put it through the wringer

I have been using these water bottles for a number of years now. I think I'm on my fourth or fifth. The only issues is they can be difficult to clean after adding electrolytes, since the opening is so small. The same goes for filling. I frequently lose the clear cap, but that's not a deal breaker. These are still the lightest, best designed bottles out there. I love being able to roll them flat when they're empty.

Is it compatible with sawyer squeeze?

It would just be compatible with other platypus products.

Hiking and Traveling

  • Familiarity: I've used it several times

I'm a die-hard Hydroflask girl. I love the insulation and colors, but the trade off was how heavy those insulated water bottles are. I love the soft bottle. It is perfect for taking on snowy hikes when I don't necessarily want cold water. It is the perfect travel water bottle and great to take through TSA. The only problem is cleaning the bottle because a standard brush can't fit into it. I only put water in this and then rinse it with vinegar at the end of hikes. That seems to do the trick.

Lightweight & Great for Packing

    Perfect, glad that I made the switch from traditional hard bottles for my last backpacking trip! Great for the extra bottles to fill a pack.

    Shaving unused weight

      I just picked up a few of the 1L Platypus Soft Bottles and they have quickly become a must have for any backpacking set up. They roll up small and the cap doesn't get in the way of much. Great for carrying water from the source to your camp. When you're finished you don't have to worry about the excess weight of a traditional bottle.

      0.5 Liter for the Win

      • Familiarity: I've put it through the wringer

      There's really nothing to these bottles. They are very flexible and light. They can roll up very small when not filled. I love them for anything in the backcountry. I love them for simple day hikes VS a hard bottle so you don't have a hard object either jamming you in the back or taking up all your space in your small pack. Just buy these if you do anything where space matters.

      Good water container

      • Familiarity: I've used it several times

      Used this one for my daily drink mixes and it worked well. Only improvement would be an elastic band to keep it stored in the rolled-up position when empty.

      Many uses

        SO MANY USES:
        Extra hydration in the bike pack for extra long rides.

        Packable and lightweight extra hydration while backpacking or hiking.

        And they are awesome as frozen ice packs in the cooler for the weekend - creates a nice hunk of ice, AND you have cold water to drink once it melts, so you are using that cooler space more efficiently. BUT, you must be careful not to freeze them if they are too full or you will break the seal. Their older, first generation plastics seem to have held up better for me, but I totally understand they are not exactly intended to be ice packs.

        Great compact bottle

          I bought this to be a compact bottle and it is what it states, light weight and compact. Used it and it did not leak, the only draw back is getting it to dry out afterwards.

          Great Packable Water Bottle

          • Familiarity: I've put it through the wringer

          This soft water bottle is great for storing extra water while hiking or backbacking. It is durable, doesn't leak at the cap, and pack down to almost nothing when not in use. It is great for carrying extra water on longer days or into camp for cooking. Highly recommend this bottle as an alternative to large nalgenes.

          Good Product

          • Familiarity: I returned this product before using it

          This was a good product but I got the wrong size so had to return this one.

          Awesome water bottle

          • Familiarity: I've used it several times

          The Platypus SoftBottle is such a great little travel style water bottle. I love how packable it is, even in the 1L. It is extremely lightweight, and you can roll it right up and toss it in a bag without even knowing it is there. However, I find it not quite as durable as the Platy Plus bottle by Platypus, because it is more of a plastic material than than rubberized (like the Platy Plus is). I really like the twist top lid feature on both bottles through. I just don't trust the Push/Pull caps when full with water and in your pack with a lot of your valuables. Overall, awesome travel bottle though, and would highly recommend!

          great for trouing

          • Familiarity: I've put it through the wringer

          I use this bottle when i am out skiing. It packs down really small and holds up way better than expected.

          Best Space Saver

          • Familiarity: I've put it through the wringer

          I love this. I was tired of carrying a big Nalgene or Hydroflask in my bag when touring that took up a ton of space. I was super stoked to pick this up. Even when full it takes up less space than a regular bottle. Love it. Buy one.

          Fits in your pocket

          • Familiarity: I've used it several times

          I have a couple of these in the 0.5L size. I keep them in my ski jacket when I'm tooling around the resort so that I can have water but don't need to lug a pack around. When you're done they roll up and fit in there even better.

          Sip it up

            I've been using one of these for a few years and have had no issues. I have a regular cap and a sippy cap I stole off another bottle.

            Lightweight and Pack-able

            • Familiarity: I've put it through the wringer

            Platypus bottles are a must have for anyone looking for a lightweight alternative to a standard water bottle. I use mine for ski touring, hiking, backpacking and much more! Once you finish your water it flattens down to save space in your pack.

            Convenient Until Cleaning

            • Familiarity: I've put it through the wringer

            This is a great water bottle for hiking, backpacking, touring or really any time space and weight is limited. I've had great luck with these and am yet to have one leak or break. The only downfall to these is that they are difficult and take a long time to dry after washing.

            Unanswered Question

            How can I get mould out of my bottle? I may have forgotten it with leftover Gatorade inside....
