Review on Ultimate Hydration Backpack for Outdoor Activities: 2L Bladder, Bite Valve, Zippered Pockets by Daniel Jackson

Advantages: - The color is fantastic. Can still look girly while working out. The water is at your back which keeps it from freezing in winter and appears to be in an isolated area (see image). The other part of the book bag leaves enough room for a shirt and some camping gear.- The way the water hose wraps around itself means the hose doesn't kink. Cons: - The water hose wraps around the front making the bag difficult to remove and attach easily - The hook holding the water valve is difficult to remove and attach to the clip - The initial installation of the hose to the der Water bag was very difficult to insert but does not leak
