Great for marathon training
This is exactly what I need. You get 2 bottles for the price of one! So you get great value compared to what you pay. It had a weird taste the first use, but eventually it went away. It fits into my running vest perfectly. And as someone who is training for a marathon, it has great storage capacity.

Will buy more.
FIt perfectly in ubofest vest front pocket. Function as expected, no leaks or anything. The opening is big enough to clean easily.. I'll buy more.

Nice fit, faulty parts.
I purchased these for a running vest as they are shorter and squatter than most other flasks of the same volume so fit better and doesn't flop around well running. In that regard they're great, however the internal rubber o-ring on one snapped within a few uses(came out when unscrewed top). Without the o-ring it's useless for me as the pressure of the vest when wearing it will squeeze out most of the water, leaving me drenched and dehydrated. So unless I can find a replacement oring or top, it's garbage now.

Great for running
These are great for running! I can fit both in my phanny pack or carry it by hand either works. I usually only finish one but have the other for my running buddies

The smell!!! and can't get water out
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!!!

Great for on the go and also for on the low
These work great!! I ordered them so I could sneak liquor into a rave and it worked perfectly. I definitely plan to use these more in the future, they’re great for on the go and also on the low! Would definitely recommend!

The flasks look good and seem well made. I haven't used them yet but there is no smell to them inside or out and the nozzle is sealed in plastic when it arrives. They are very compact for transporting in your luggage which is great and the colour is as described. Looking forward to using them for lots of hiking.

Great product!

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
