User Review: CamelBak UnBottle
Price Paid: $27
This is simply a great dromedary bag -- I used it as my primary water storage for the trail when hitting the backcountry in Zion recently, and it was just a simple bag to use.
Your water stays cold -- which is nice when it's 107 degrees F outside (I presume it would remain hot as well, but never opted to try that in the heat I was facing!). Your water stays put -- the locking mechanism is secure and easy to use. Your water tastes good -- no plastic aftertaste at all! In short, it's all you'd want it to be.
I had to ding it 1/2 star due to the bite valve coming off. More accurately, it would come off when I did something to pull it out accidentally (such as pulling on my pack and not realizing it was twisted under a belt or whatever).
The design is a good one: you can replace the bite valve as needed. However, I would prefer to see a little bit tighter seal so as to not have it pull out quite so easily as it does. That said, if you are a bit more observant and less clutzy than I, you may find this to be a non-issue. :)
That said, if you need a very solid dromedary bag, this is the one to buy. Highly recommended!
