Hydration Pack Backpacks with 2 L Backpack Water Bladder for Hiking, Cycling, Running, Walking and Climbing . Fits Men and Women with Chest Sizes 27" - 50" by KISTAR (Black)

Wore during a Tough Mudder and it did better then the expensive I had. Durable, didnt leak like the other one I had. I love the fact the mouth piece can be locked and unlocked. Was very easy to clean and the extra pockets were great for holding my other necessities I needed to get through my race.

I bought this for my husband and it leaked all over. When it arrived, I cleaned it and filled it at home before our hiking trip. I loaded up our hydration backpacks in our van and when we arrived to the hiking area, we took out our backpacks and noticed that this one was almost empty and soaked!! The other three i purchased were different brands and colors and were perfectly fine. Had to return it.

The bag is good. The hydration pack leaks and I have had major issues with it.

Its nice that I can fit all of my must haves in here, but the part where you suck the water out leaks. Like really bad. When I take it to raves it leaks on my clothes and all over the floor. Please fix this.

It was perfect!

have to tighten or will leak, great deal

Water bladder leaks. Backpack itself is ok, but some of the stitchings have come loose. I only used it once. I had to use Saran Wrap around the bladder to keep it from leaking further.

Very happy with this so far, used it once and didn't have any issues with leaking. There is also a very large pockets for extra storage in the front.
