## Customer Reviews

### ⭐⭐⭐⭐⭐ Great! Did well in my first marathon!
*by A***M on September 9, 2024*

I purchased this with the Aonijie vest and it worked great in my marathon. There was some sloshing around but I think that was my fault because I didn't get all the air out beforehand. Easy to clean and no leaking. I really like how the bag seals compared to other bladders. You seal the bag by folding the top and running this plastic bar across the top which is 100% leakproof compared to other bladders where they use a twist cap method that is prone to leaking over time. Definitely recommend!

### ⭐⭐⭐⭐⭐ Well designed hydration system
*by J***T on June 29, 2025*

This fits really well into the Aojinie hydration vest. The seal at the top the bag is very snug so that water doesn’t leak out and water flows easily through the tube. The nozzle can slide to On for when you want water, then you can slide it to an Off position so water doesn’t flow back down the tube. The water tasted like plastic at first, but that has gone away with more use. You could probably flush it with a lot of water, too

### ⭐⭐⭐⭐ Solid small water vest
*by C***K on March 19, 2024*

I use this for outdoor activities where I need easy access to water. The most common use cases are skiing (under my shell) and cycling.Overall, I like the pack and the bladder - especially the simple fold-over close mechanism - so much better than the screw-in closures. However, the tip leaks ever so slightly. I really noticed this while skiing where my vest and undershirt got wet - not horrible, but about 4" across. I 'solved' this by blowing water out of the tube when I finish drinking. That's not optimal for me so I'll be looking for a way to fix that (maybe replace the bite-valve).I'm 6' 4" 185 lbs - so tall but not particularly large. I think the vest fits fine. It can be a bit larger if I adjusted the straps for more room.One thing that I figured out after a few times trying to drink is that the valve has a push-in lock and pull-out open mode. Even with that, it's still leaks slowly.
