CamelBak Crux Lumbar Reservoir

The Lumbar reservoir is specifically shaped to sit lower on your back, near your waist, rather than vertically along your spine. This design helps lower your center of gravity, which can improve stability and comfort during technical trail rides or hikes.

This reservoir is designed for packs specifically built to accommodate a lumbar-style reservoir. While it may fit in other packs, the unique horizontal shape might not sit correctly or securely in standard vertical hydration sleeves.

The Crux system is engineered to deliver 20% more water per sip compared to previous models. This is achieved through a redesigned tube and bite valve that allows for a higher volume of water to pass through with less effort.

The Big Bite valve is self-sealing, meaning it automatically closes after each sip to prevent drips. Additionally, there is a dedicated on/off lever on the tube that you can manually engage to completely seal the system when you want extra security against leaks.

Yes, the reservoir is constructed from BPA, BPS, and BPF-free materials, ensuring that no harmful chemicals leach into your water supply.

No, this is a non-insulated reservoir. If you are hiking or riding in extreme temperatures, you may want to consider using a pack with an insulated sleeve or adding ice to the reservoir to help keep your water cool.
