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. There’s also an internal baffle that reduces sloshing and slims the bladder's profile, making room for more gear in your pack. 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).
