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

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.

Is the duo lock 2 liter screw top compatable with the Sawyer mini water filter

Hey there Dan!

It looks like that Sawyer is not compatible with this or the seeker bottle from hydrapack. I would check out the Vecto Water Container which I don't carry or the Sawyer Fast Fill Hydration Adapter! Feel free to contact me for more information or hop on our live chat or even call in!

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.

    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.
