Crux Lumbar Reservoir

  • Familiarity: I've put it through the wringer

The Crux Lumbar Reservoir is great. It is a perfect match for my pursuit 24 backpack. This lumbar back is awesome saves a lot of space in the back rather than having a bladder.


  • Familiarity: I've used it several times
  • Fit: True to size

A perfect replacement bladder for my Skyline pack. Quick release hose makes refilling easy with out having to remove hose from pack.
