Platypus DuoLock SoftBottle

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!

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.

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.

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 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.

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.

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.
