Review: Easy Hydration solution - I have been using these for years now. Never leaked, i keep them in the freeze between uses & there is no taste or smell from them. They are so convenient, i have used them in my hydration pack, waste belt & also put one in my running shorts pocket, for short warm runs. The fact they roll up when empty is good for longer runs, better than hard bottles.
Review: Great for hydration on longer runs - I bought these for use in my running vest and they are ideal. Quite difficult to get rid of the chemical smell/taste but I think that is a common thing. Unfortunately after a few months use I got a tear in one of the bottles so I'm down to having only 1 left. Guess that's just a bit of a hazard with these being the softer material

## Features

- MATERIAL: Made of food grade TPU, the water bottle is soft and collapsible. There may be a small packet of tea leaves in the bottle, which helps get rid of plastic smell and is harmless. Please throw it away before filling with water
- SPACE SAVING DESIGN: The collapsible water bottle stands upright when it is full of water, and can be folded into a small size when not in use, making it easy to store and carry
- EASY TO DRINK & CLEAN: The running water bottle with a nozzle or straw makes it easy to drink while exercising; In addition, the wide mouth is convenient for filling and cleaning
- PRACTICAL: TPU soft flask can be refrigerated (non-freezable) so you can get fresh drinking water on hot days; (Recommended temperature: 0-40℃)
- EASY CARRYING: The foldable water bottle for hydration vest is suitable for running, marathon, jogging, cycling, hiking, backpacking and traveling; Outdoor sports water bottle that can be used by both adults and children

## Questions & Answers

**Q: I want to carry this in place of a plastic deer park water bottles for a running belt. Will this swap work?**
A: Probably not. This bottle is completely collapsible, and when the water level gets low, the straws cause the bottle to sag.

**Q: Does this start to collapse when you drink? I want to omit hearing the water sloshing sound when I run?**
A: Yes, it is. You gonna listen anithing. It is perfect for running

**Q: Do all of the sizes and packs of 2 come with the straw?**
A: No. The 250ml and 500ml did not come with the straw.

**Q: Will this work with osprey enduro 6?**
A: Sorry, we can not judge if the bottles can work with the osprey enduro 6. We suggest that you can contact with Osprey to ask about the size of the bottles pocket..

### ⭐⭐⭐⭐⭐ Value matches purpose
*by A***R on 5 July 2025*

I do not like to use hydration vests (personally) so I have a belt and the 500 fits perfectly in there. This is a plastic product and used regularly so I guess it will start leaking at some point but overall nice product.
