Perfect for my needs
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!

Very functional
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

Works great, will stain
These are great! Love that they fit in my hydration vest pocket so I can have clean water in my vest and electrolytes in these. Only bad thing is they stain with colored electrolytes. But who really cares.

Great product
I love these water bottles. I use them on motorcycle rides. When Iâve 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.

Great durable bottles
These work great. I used them for a 100 mile ultra marathon. Quick and easy to fill up at aid stations. I store them in the freezer after washing them to prevent mildew.

Made well, but makes your water taste horrible
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.

Great for running vests
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.

Producto original. Tarda un poco en desaparecer el sabor a plástico. Pero es excelente. Son 2 botellas de 500 ml c/u

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

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

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