AONIJIE 2 Pieces Foldable TPU Outdoor Sports Water Hydration Bottle Soft Bottle for Running Camping Hiking Cycling (500ml-2pcs)

Used these squishy bottles for a while. Eventually they do start leaking, (maybe after a year) but I use them every day nearly in my run vest punding the trails

Best tip with any drink bladder or bottle is to run hot (tap hot) water through them for 10 mins before using. Plastic taste completely disappears. These are great value for money and come in plenty of different configurations. My only slight issue is with the size of the fill hole. Bit awkward for putting any powdered product into them. I do have bigger ones, with straws and they are great.

Great to have in your pocket/bag and when in use, to carry in your hand/pocket.Super space efficient and light.Reliable and useful product I will continue to use.

I have been using a Mountain Warehouse 'rollable' flask when running. Its ok but has a slightly flared shape which means its difficult to get in a pocket, and the material is horrid. It will roll up into a tube but is otherwise not very flexible and I was worried it would split.I bought these soft flasks after looking at options including better known brands such as Salomon. As is usual, no clear winner emerged so I decided to go for this offer of two flasks for £15.I was nervous I would be able to detect the plastic taste other reviewers mention. Happily, the water from mine tastes ok.Good:* Collapsible soft flasks* Great value* No plastic taste* Fits my running vest wellBad:* NothingConclusionI'm really pleased with these soft flasks. There is so much choice it can be difficult to make a decision. I would recommend these to anyone looking for 500ml soft flasks.

Used these for a multi-day desert ultra as my back up water carriers. Good enough for this as they were fine when upright in my bag but would slowly leak if I leant forwards or laid them down in my tent.Good enough for one (long) race, but would buy different ones if I wanted long term bottles.A number of previous reviews complained about the water tasting bad, but even at 55 degrees centigrade, the water tasted fine.

These are ideal for long run training and are compatible with many backpacks. They don’t leak which is the first so I’m very pleased.

There's no proper seal on these bottles. I filled it up and left it in a bowl with no added pressure of things pushing against it and within 20mins there's was a puddle. Definitely will never be used have had to throw away! Stay clear!

I’m an ultra runner and use these regularly. You get 2 x 500 ml bottles which don’t leak (my bug bear) and are really easy to drink from. I wear them in the front two pouches on my Solomon 10 backpack. They slot in with ease when full. I prefer these to a camel pack but often take both depending on how far I’m going. I Can’t believe there’s been such limited reviews! I must have just struck lucky!!!! Definitely recommend and I’ve tried every drinking vessel going!!!!

Je les adorent sknt parfait pour mettre dans mon sac d’hydratations et se lave tres bien

aprendí que no debo dejar agua por varias horas porque se amarga...y por el precio, están bien.
