Trek into unknown adventure with the confidence of clean drinking water. The Crux® 2L Reservoir Filtration Kit filtered by LifeStraw® carries 2L of water that pass through two separate stages of filtration for safe hydration. 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.
