AONIJIE 2 Pack Soft Water Bottle, TPU Collapsible Flask Foldable Bottles for Hydration Pack, BPA-Free, for Running Hiking Cycling Climbing (2 Pcs - 500ml)

I have a 50 miler race coming up that requires to carry some sort of water flasks. The race itself is cupless. These are the cheapest and very good quality flasks I found. Overall, I'm impressed by their quality. They are leakproof and comfortable to carry. The bottle are of high quality. I put tailwind and water in it, that was very easy to clean. The ones I bought were 2x 500 ml

This is working perfect for our needs. Bought these for a family member and they've been used for over a month now with an average 5k/day for hiking/running. Fit and weight are as expected. Smell was very minimal and disappeared after a washing and no leaks so far. Thank you!

Leak proof. Very durable and the quality was amazing. The size was perfect for my vest. I’m very happy with it.

These flasks are fine for replacements in my hydration vest, but they’re a little hard to get water out of. You have to really bite and suck hard compared to the flasks that came with my vest. But these are no different from any other replacements you can buy on here.

Durable, easy to fill/clean, and just the right size for my medium long runs. I have a hydration vest from the same manufacturer and this soft flask fit perfectly into its respective sleeve on the vest. The best part is how solidly leak proof there are. Knowing they won’t leak makes me feel a lot better about traveling with them or just throwing my vest and bottle into my vehicle after a run.

I love these water bottles. I use them on motorcycle rides. When I’ve emptied one it folds up to practically nothing. You do have to use them a bit to get rid of the plastic smell, but it never really bothered me.

Bought these to replace my Salomon flasks- work perfectly. Easy to clean and accessible to drink out of while running. Fit in my vest well.

Bought these for music festivals as they're smaller than a camelback and fit in my pocket when empty. Great for the crowds and mosh pits. After months of use they've held up well. They survived 2 festivals, a camping trip, and a couple vacation trips. But the reason they get 3 stars is that, even after at least a hundred refills and all the use they've seen, they still leach something into the water in them that makes it taste horrible. I'm probably going to look for new bottles of similar design that are made from better materials that won't leach chemicals into my water.

El flujo de las boquillas es pésimo, sumado a lo pequeño del orificio para rellenarlas. Arrepentimiento total

Me gustó mucho la comodidad y ligereza. Solamente pondría un pero en la válvula, que deja pasar muy poco líquido a comparación de algunas otras marcas.

Got these for my husband, but you cant clean the mouth mouth of the straws with a pipe cleaner…. And that means bacteria can get stuck and grow mold gross

Cumpre o que promete.

Slightly disappointed with these. Found the bottles to difficult to drink from as the flow from the bottle isn’t too great and requires effort to draw fluids from. I’m hoping this gets easier, the more I use them but not holding out much hope.
