Camelbak are kind of known for their standard-setting reservoirs, so it’s hard to believe that they were able to improve on them, that is until the Crux™ reservoir came along. The Crux™ 3L Lumbar Reservoir is designed exclusively for the Camelbak Low Rider Packs which offer added stability when you’re on the move.

With a larger access port, you can top up your water supply much quicker and easier. This reservoir is also going to deliver 20% more water per sip, so you can hydrate faster with less effort on your part. You can close off the drinking tube with one hand when you’re mid-action, and the bite valve is self-sealing so you won’t get any leaks or drips mid-run, hike or ride.

With the addition of baffles, your reservoir will keep a low profile in your pack and won’t slosh around as much when you’re in action. The reservoir and tube are made using antimicrobial technology which will assist with inhibiting bacteria growth, so you can keep your water supply fresher and cleaner for all your active pursuits.

  • 20% more water per sip
  • Quick Link system to disconnect the drink tube easily and remove the reservoir from your pack
  • Auto shutoff valve to prevent leaks
  • Reservoir baffles to reduce water sloshing and keep reservoir low profile
  • Lumbar design shifts water weight to your lower back for more stability Leak-proof cap
  • On/off lever lets you seal your drinking tube shut with one hand
  • Bite valve self-seals after use

Great product

Was sick of using water bottles and having to get them in and out of my pack .... along came Crux ... great product, sits well in my day pack against my lower back, comfortable, easy to fill and so far, delivers the water!!!!

Good shape and size

Thsi short wide the 3 ltr version is better in the pack as it doesn't hang down and get covered with gear like my older long 3 ltr. Same quality and quick detach hose and I like the new drinking valve.

5star Quality Product

So much better than the 'old' camelbaks
Larger sip, no leaks and easier to handle when filling. Draws every last drop from reservoir
Fits nicely in bottom of bag so doesn't block access to other pack items

Difference between the Lumbar and Reservoir?1 answer

Hi Guys, just wondering which would be better for larger backpacks or what the difference is regarding the Camelbak 3L Lumbar, or the Camelbak 3L Reservoir? Both are available on your site and apart from the shape, are there any differences or benifits for one over the other? Cheers.

Hi Aaron, for regular trekking packs the standard 3L reservoir would be best, it has a long thin shape that suits sleeves or hanging points fount inside most packs. The lumbar reservoir suits specific Camelbak running and daypacks that are designed with a compartment for the lumbar reservoir low down on the pack.
