Very compact
Bought this for my granddaughter as she was going to a festival, it was great to fill when she needed a drink and she was able to fold it away when she finished. Good quality

Great product, great concept...but maybe not for everyone.
Lightweight and folds up neat and small (when empty of course). But, maybe it's just me, but it's quite awkward to drink from what is effectively a plastic sack. I'm not sure I enjoy the floppyness of it, and the fact that you have to both bite suck at the same time. And filling it up is a bit awkward.. fine from a tap, but if you want to pour something from another bottle into it, than it's pouring from a bottle into a bottle i.e. expect spillage. May also need a few washes to get rid of that chemically plasticy smell. The product itself is fine, sturdy, leak proof and all that. I love the concept of it... but it's not as great as I was hoping.

Very compact
I love this bottle for it's compact qualities. There is definitely a plastic taste sometimes, but it goes away with some good rinses. I took this on a trip to Italy and kept it in my Uniqlo cross body bag the whole time, it fit great. I got the smallest size, which I regret a bit because I would drink the whole thing in 1 gulp, but otherwise, I really liked how flexible it is. The only big issue was that I find it really hard to unscrew the cap to refill it with water, it's just hard to get a good grip on the bottle because it's so bendy and squishy.

A very good foldable flask for drinking healthy water
It might e a bit expensive but it is a much superior to a normal plastic bottle. It's foldable and excellent to have in a pocket at the gym, or on a walk somewhere. It is unlikely to leak thanks to it's suction mechanism. However, I am using it only for still water. Once I tried sparkling water and it became inflated like a little balloon. I think this product would be very tricky to use for any tea, milk or coffee, so I would recommend it for drinking healthy water only.

Lightweight Design but Strong Plastic Smell Was Unpleasant
The soft flask is lightweight, flexible, and easy to carry, which initially made it seem like a practical option for running and outdoor activities. The collapsible design is convenient for saving space, and the bottle itself fits comfortably into running vests and smaller pockets. Unfortunately, the strong plastic smell was a major downside. Even after rinsing and airing it out multiple times, the odour remained noticeable and affected the drinking experience. Because of this, it was difficult to feel comfortable using it regularly for water during exercise. The overall idea and portability are good, but the material quality did not meet expectations in this case. I also expected a cleaner, more neutral taste and smell from a reusable hydration flask designed for sports use. As a result, the product was ultimately returned. Overall, while the design is practical, the strong plastic odour significantly reduced the usability and overall experience.

Useful, but awful taste.
We took these snowboarding as wanted something soft in our backpacks incase we landed on them. For that purpose, these were great! Soft and lightweight, and didn’t leak. BUT… the awful taste!!! The water tasted almost chemical after it had been in there for an hour so.

Falsche Größe angekommen
Hatte von der Marke schonmal eine Flasche bestellt, die war gut und hält dicht. Leider habe ich im 2er Pack 150ml Flaschen anstatt wie bestellt 250ml Flaschen bekommen.

Unangenehmer Geschmack
Der unangenehme Geschmack macht Wasser aus diesen Flaschen ungenießbar.

Great for Races and Trail Runs
Bought these to try out for trail running and I’m very happy! They are super light and take up very little space in my running vest. That makes them great for trail running and short hikes. I used one for a 12 mile mountain run last weekend and had great success. No leaks, easy to open, easy to drink from. I’m very happy with them and would purchase again or recommend to other runners and hikers!

Zufrieden
Find die Trinkflasche für den Sommer super, weil sie wirklich klein und handlich ist. Material riecht intensiv nach Plastik.
