Outfit your pack with flexibility and the built-in confidence of clean and safe drinking water. The CamelBak Crux® Reservoir Kit filtered by LifeStraw® passes 2 liters of water through two complete stages of filtration - the Hollow Fiber Filter removes bacteria, parasites, and microplastics and the Activated Carbon Filter reduces taste, odor, and chlorine.

　　The wide-mouth fill port includes a tethered leak-proof cap and ergonomic handle for a sturdy fill. An on/off lever prevents unwanted drips and the Big Bite Valve self-seals after each sip. Hydroguard™ anti-microbial technology inhibits the growth of bacteria in the reservoir and tube, and all components are free of BPA, BPS, and BPF. Pack assembly is a breeze with an easy-to-load low-profile reservoir baffle and Quicklink™ System that features an auto shut-off to prevent leakage. Convert into a gravity bag by pairing with CamelBak's Reservoir Gravity Kit (sold separately). Safe hydration, trustworthy filtration.
