Review on Stay Hydrated Anywhere with the CamelBak Classic Hydration Pack, 85oz by Joseph Meola

The packaging itself is fine. Lightweight and exactly as advertised. The problem is in the bladder. When tightly closed, it allows plenty of water to pass through the fill hole. I trusted the camel's name and bought it without reading the reviews. Oops. Too bad I will never trust this brand again. There are many other good options for balloons and hiking backpacks. The problem seems to be the hard plastic used for the screw cap. I'm not sure if this is an R&D or manufacturing issue. Stay away from it.
