      Ease of use. Water bladder issues solved!

      Size: One Size  |  Posted: 5/28/2020

      This is the easiest, cleanest, and strongest water bladder that I have used. The company did not just make a bladder, they designed one based on problems with others, and solved the problems that we all have had. The on off valves-check! The fill-neck-handle-check! The quick disconnects-check! Lockable fill port-check! Sturdy/tough-check! No leaks-CHECK! You will like it too!

      Bottom Line: Yes, I would recommend to a friend.

      non-leaking and doesn't sway

      Size: One Size  |  Posted: 7/7/2021

      Running with a back reservoir takes getting used to. The baffle does a great job preventing the water from sloshing from side to side. The nozzle works well, none of the openings leaked, and the magnetic clip work great. The container has no unpleasant odor or taste and I use it with a Nathan hydration vest.

      Bottom Line: Yes, I would recommend to a friend.

      Easy to fill

      Size: One Size  |  Posted: 5/30/2020

      Needed an extra bladder for my Nathan Vapor Air. It is heavier than my other reservoir due to the plastic flip lid. But much easier to fill on the run rather than having to remove the slide clip and unfold the top of the bag on the Nathan reservoir. Opening is small so those with larger hands may not be able to clean inside as well without a bottle brush. Mouthpiece works well and does not leak. Flow is good. Included magnet to secure the tube/mouthpiece to your running vest stays put. Price is good. If you need the lightest reservoir possible - this one is not for you.

      Bottom Line: Yes, I would recommend to a friend.
