Exactly what I expected. Works much nicer than carrying a water bottle on my mountain bike.

We used these at an outdoor event over 7 days. They worked very well. No problems.

Not as good as my old Camel Pak. But half the price for two.

i've used these hydration packs on a couple of hikes and bike rides and they have done what i've wanted them to do... hold water. they are very sturdy and are pretty easy to use. the only thing that bothers me is how little the pocket is for carrying things... i can fit my keys a phone and a small digital camera in it and that's it. for how cheap they are in price it is a very good deal... they are good quality hydration packs.
