    Absolutely fantastic hydration solution
  

*by Y***. on Reviewed in the United States on July 23, 2024*

Lightweight, excellent sealing, and slim.Well shaped, fits into my running vest (I use Nathan) and even in pants with large pockets.It's a very functional hydration solution (I don't use the long straw), and I use it daily

    So lightweight!
  

*by L***L on Reviewed in the United States on April 15, 2024*

Bought these to put in my vest for training for a marathon. I love how light weight they are and easy to refill! Awesome that I can put them in the dishwasher and not worry about left over taste from electrolyte tabs.Because they are so flexible, a vacuum is created as you drink from them. So at first when the bottle is full, it can stand on its own. After the first sip, the water stays at the top of the bottle in the mouthpiece and the bottom of the bottle starts to curl upwards and suck into itself and it can no longer stand on its own *unless* you blow air back into the bottle to give it shape again. Completely empty, it lays flat on itself and is quite small. See pictures! Some reviewers were mad about this feature but that is how they were designed- to be slim and lightweight for exercise vests/belts, not for carrying by hand and resting on tables.Looking at buying more in different sizes!

    Functional & Durability
  

*by H***R on Reviewed in the United States on June 28, 2024*

Fabulous soft flasks. The “speed” option is nice for quick transitions in races. Durable. The 600ml is a nice size & allows a bit more room for liquids over the 500ml option, while still being super compact-able when empty. The 600ml fits well into storage pockets on a number of hydration vests.
