AXEN 500ML Soft Flask, TPU Foldable Running Hydration Flask, Soft Collapsible Water Bottle for Hydration Pack Cycling Marathon Running Hiking

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

Feels good material, does not seem to leak. Had very very strong taste only briefly rinsed before filling and trying to use, felt like burning lips. Suggest rinse a lot to clear the taste before use.

Great product, good size fits neatly into palm. Good leak proof nozzle and dust cap keeps it clean. Has bite release valve which is easy to operate. Only down side is chemical taste from bottle despite washing and leaving to soak overnight. However using the bottle with flavoured electrolyte drink masks the taste. (Just). The 150ml size is adequate for shorter runs. For 10k and over a bigger size would probably be required. The twin pack is good.

Very useful and light weight. These replace similar product I’ve used on many trips and lasted 4 or 5 years. Far more practical than a hard bottle. These look good and passed their first outing with flying colours. Like the captive top to the outlet.

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.

Nicely made but there is the most disgusting burned rubber taste when you draw on it which stays in your mouth. I've washed and soaked it but it persists. So unusable.

It works well and rolls down small, perfect for running and holiday. The water gets very warm though. Light weight and didn't leak !

This is superb solution to taking liquid with you on a run (or on a trek). Its flexible design means that you can easily stash it in your pocket, or a running vest. The compact design also minimises how much the water swishes around, keeping it colder for longer. The material is tough and feels strong and secure. I have been using this as my primary go-to for 5k’s. This is a must have for all sports fitness.
