CamelBak Crux Lumbar 3L Reservoir Hydration Water Bladder

Engineered for adventurers who demand both comfort and performance, the CamelBak Crux Lumbar 3L Reservoir delivers maximum hydration while maintaining a low center of gravity. Unlike traditional reservoirs, the Crux Lumbar design places the weight of the water on your lower back, helping to improve stability and reduce fatigue—especially during long hikes, mountain biking, or trail running.

With its high-flow Crux technology, this reservoir delivers 20% more water per sip, so you can stay hydrated with less effort. The Quicklink™ system allows for easy hose removal and reservoir refilling, while the wide, leak-proof screw cap makes it simple to open, fill, and seal—even with gloves on.

Constructed from BPA-, BPS-, and BPF-free materials, it features Hydroguard™ technology to inhibit the growth of bacteria in the reservoir and tube, ensuring clean, fresh-tasting water on every outing. Designed for use with lumbar-compatible hydration packs, the Crux Lumbar 3L is a reliable companion for demanding outdoor adventures.
