CamelBak's streamlined HydroBak carries 50 ounces of fluid, the equivalent of two large water bottles. The over-the-shoulder tube provides easy access to liquid refreshment and the breathable mesh harness keeps you feeling great. The HydroBak is compact and has a low profile so it's stable and out of the way. Plus, it has an external zip pocket for keys and other essentials.
CamelBak's Antidote bladder is the pinnacle of easy function and convenience. Its huge mouth means easy filling and cleaning (you can even get a hand inside), plus it opens and closes with only a quarter turn. Built into the mouth are fold-away arms for quick and easy bladder drying. You also get CamelBak’s HydroGuard bacteria protection so your water stays fresh and clean. What's more, the Antidote features their innovative Quick Link system that lets you detach the hose (there’s an auto shut-off) for refilling without pulling the entire system out of the pack. It also lets you easily add CamelBak accessories, like their Fresh Filter and Flow Meter (sold separately).
