These work great - no leaking, fit perfectly in the pockets of my hydration vest, and as the water level goes down, no sloshing. Easy to clean.

Bought these to carry inside of running vest to switch out on long runs. Perfect and know leaking in back of pack.

These fit very well into the accompanying vest and are easy to use during long runs. I used these when training for a half, they’re good quality, spill proof but also easy to drink from when running. The only downside is they are very difficult to clean.

The awful smell of plastic and chemicals in this is overpowering and disgusting! The advertisement says odorless and that's a lie also getting the water out was rediculous! After cleaning I had to remove the top to get water out then took 20 min to get the awful plastic taste gone with food. What in the world is in this. I felt like I'd been poisoned. The ad says odorless but they give you instructions to clean it!!! Didn't work! Can't get the water out but it shows a girl just pouring it into her mouth!!! Misleading and wrong!!! Not happy!!!

Perfect in combination with the 1.5-3 ltr. Bladder’s for my long runs. Ultra Runner:OneMoreMile50kQuality is excellent. I bought the larger bottles and bladder’s also and switch them out based on my distance I am running. UTOBEST is amazing.

These work GREAT in my Nathan hydration vest! I love that they actually open/close by pushing/ pulling the mouthpiece.

Perfect for amusement parks to keep water with you on hot days. Easy to dump and roll up and put in your pocket when you’re getting on a ride. Don’t have to worry about leaving a bottle in the storage bins. Has a slight plastic after taste but it’s small enough that you’d finish the water before it was a real issue
