Rated 5 out of 5 by from It works extremely well for a child I bought this a month ago for a very small child. She drinks out of it everywhere we go best hydration set up. No leaks no mess it's great. And the child can easily operate it. Bonus feature is extremely easy to put in the child's backpack and easy to take out and extremely easy to refill

Rated 4 out of 5 by from Quality product for a good price I bought this a month ago to replace my Nathan Pack Bladder. It is not a perfect replacement, but I believe that Camelback's mouthpiece is much simpler than Nathan's mouthpiece and it's easier to disassemble. I have never been a fan of the screw-top camelback system, but overall you cannot beat their bladders.

Rated 3 out of 5 by from Larger diameter drinking tube CamelBak introduced a larger diameter drinking tube to allow 20% more water per sip. The main issue with that is that the tube collapses and kinks much easier than the original tube. Secondly the larger diameter tube makes it harder to clip into older hydration bags tube clips. Using this hydration bladder in an older hydration pack as a replacement may not be ideal. It works as advertised on the new bags that are designed around the tubes limitations.

Rated 5 out of 5 by from Good just got better! The new design is a lot better than the previous one with some big improvements. The lid seals a lot better. Nothing worse than having a volunteer at an aid station try to get the lid on correctly. This design is fast and easy, so no more water coming down your back when it isn't sealed right. The new valve is awesome, and won't be coming apart like the old design. Thanks Camelbak!!
