Convert your pack into a powerhouse water filter. The Reservoir Filter Kit filtered by LifeStraw is an accessory that conveniently snaps in place between a CamelBak reservoir and the tube via the Quicklink connection. Two stages of filtration provide safe hydration from just about any source. The Hollow Fiber Filter removes bacteria, parasites, and microplastics and the Activated Carbon Filter removes taste, odor, and chlorine. The Filter Kit accessory rinses clean and is free of BPA, BPS, and BPF.
