The CamelBak Crux® Lumbar 1.5L Reservoir is a streamlined hydration bladder designed to sit low and stable, delivering efficient water storage without bulk. Engineered specifically for lumbar packs, this reservoir keeps weight positioned off the upper back for improved comfort and unrestricted breathing during long rides.

Featuring Crux® high-flow technology, the reservoir delivers 20% more water per sip, ensuring fast and efficient hydration on the move. An ergonomic handle makes refilling quick and easy, while the leak-proof cap is simple to open and close.

The on/off lever allows the drinking tube to be sealed with one hand, preventing unwanted leaks during transport. A self-sealing Big Bite™ valve automatically closes after each drink, eliminating drips and spills for clean, reliable hydration on the trail or road.
