Comments: I had to toss this Nathan water bottle in the trash during a 1/2 marathon. It was constantly leaking and left me thirsty with not a drop to drink. Extremely disappointing from such a typically great brand.

Comments: This is an awesome water bottle. At first, I wondered where the little cap was on the top, but there isn't one, which is great because you don't have to pop it up and down during runs. The one way valve is great and works well for taking drinks while running. I had no issues with spilling. I also found the handle to be comfortable and easy to adjust and the pouch to be nice and roomy for my house keys. I had a Fuel Belt bottle that was very similar before I had this one and this one was a definite upgrade. I highly recommend this bottle.

Comments: I just orded this and am sending it back. Perhaps I received a defected bottle, but almost 1/4 of my fluid leaked out before I even got out of the driveway. It was pretty much pouring out of the cap. Also, there is a seam on the inside of the hand strap that was irritating my skin while just holding the bottle. The pouch also seemed bulky for being oriented on the inside of your hand, like you would hit your body with it while running.
