    Staying hydrated has never been so convenient.

    Save space while staying hydrated with the Platypus DuoLock SoftBottle. Its collapsible design allows for easy and efficient storage and makes it extremely lightweight. Use it on your next run and forget you're even carrying anything by the time you're done. Or, stash it in your backpack as an extra bottle in case you won't have a chance to fill up for a while. It easily flattens and rolls flat to make it easy to carry, stuff in packs, or even stash in your pocket, and the DuoLock cap ensures it won't spill when it's full. If you don't have any space to stuff it in your pack when it's filled up, a wire gate clip lets you attach it to the outside of your bag.

    • Collapsible water bottle for on-the-go convenience
    • BPA-, BPS-, and phthalate-free plastic construction
    • DuoLock top for leak-free reliability
    • Wide mouth makes it easy to fill and clean
    • Handle and wire gate for easy carry and attachment
    • Flip cap keeps spout clean
    • Stands up whether empty or full

    Perfectly light, perfect size with clip!

    • Familiarity: I've used it several times

    This is just the best lightweight water bottle I've had. I love that it holds so much water! The clip sold me too. Good stuff.

    Platypus DuoLock SoftBottle .75L

    • Familiarity: I've used it several times

    Love this size for my hiking excursions. I purchased two of these for my backpack easy to fill and store. When you get home easy to clean and dry then just fold up and store in backpack. Ready for next adventure!! Must have for those quick easy day hikes.

    Nice packable water

    • Familiarity: I've put it through the wringer

    Perfect bottle for ski touring. Clips to the waistband of my pack and once I finish the water it packs up nice and tight. I have like five of these because I love them so much.

    What a great bottle.

    • Familiarity: I've put it through the wringer

    This is a wonderful thing, it's small and packs away nie and neat when empty, no need to carry an empty bottle around taking up room.

    Ditch the conventional water bottle

    • Familiarity: I've put it through the wringer

    This will be your new go to. I regularly go on long hikes (8+ miles) and I was blown away by how much of a difference it makes to have a lightweight water bottle. Seems obvious, but the difference was more noticeable than I thought. I was worried the plastic would be cheap after rolling it several times, but I have had zero issues with cracking. It's a little awkward to clean, but overall I love this thing and highly recommend!

    Great Buy!

    • Familiarity: I've used it several times

    Really excited about this water bottle since its lightweight and easily packs away when you're not using it. I love the clip since I often attach it to my hip back on full day fishing trips. It much more convenient than carrying around a water bottle and really cuts down on excess weight.

    Great product!

    • Familiarity: I've put it through the wringer

    Use it all the time at work. Love that it has a clip so I can take with me anywhere and easy to fill.

    Great and light and packs small

    • Familiarity: I've put it through the wringer

    the top locks great and you can clip it to anything!

    Love it!

    • Familiarity: I've used it several times

    I just got this and have used it a handful of times and have been stoked. The double lock top is great and makes me feel a little better about shoving it in a bag with my sleeping bag. Super malleable and durable. haven't had any trouble with leaking like others have, but maybe i just got lucky? not sure, but i've been stoked on mine!

    Almost There

      The 0.75L Platypus Duo Lock is a great size and design for clipping onto a climbing harness for multi-pitch routes. It's awesome at a belay in that one can the clip the bottle to a sling, leave the cap open, and take swigs between moments of rope management. However the clip would benefit from more lateral rigidity so that when the bottle is bashed around the gate is less likely to come unclipped. Another weakness of the Duo Lock is that the soft plastic at the neck, where it is fused to the rigid plastic of the cap, is vulnerable to abrasion and might not last a single pitch of chimney climbing. But it's such a great bottle that it's worth putting a few layers of duct tape, or perhaps climbing tape, over the bag-to-cap junction so the tape gets the abrasion and not the bag. Even though I got leaks in mine, I wouldn't hesitate to buy the Duo Lock again.

      Broken Clip and Leaky Bag after one trip

      • Familiarity: I've put it through the wringer

      Overall it is a nice design but not durable. During a 4 day backcountry hiking and camping trip in Canyonlands National Park I broke off the carry clip on day three and managed to get a small leak on the neck area of the bag. This was a hard use trip but I take care of my equipment and this bottle should not be relied upon for hard use. I also reached out to the manufacture after I got back to see if I can get a replacement but that has been a pain. I do like other Platypus products just not this one.

      platy cool

      • Familiarity: I've used it several times

      Awesome and so lightweight. Make sure to screw the top back on securely otherwise it will for sure leak. Folds up nice and looks rad!

      I must love it

        I keep loosing them and keep buying more.

        More, more, moreeee!!


        • Familiarity: I've used it several times

        This is a great lightweight alternative to having a bottle. It collapses easily and holds plenty of water.

        Awesome Platypus!

        • Familiarity: I've used it several times

        Purchased this to use for backpacking in some adult refreshments, without having a heavy glass bottle. Worked perfectly and the spout on this is so easy to fill when you remove the cap. I really enjoy the clip detail too when space is limited.

        Even Better

          I've used the soft platy bottles for years, they're ideal for packing light but porting a bunch of water. I'm digging the new duo lock system. The cap is snug and nicely threaded for tight closure, and a larger opening for filling up. The drinking spout is a bit smaller and locking mechanism is easy to use. I'm enjoying the attached clip as well, great for river trips or scenarios where you just need to keep everything connected.
