Osprey 1.5L Lumbar Water Bladder 

Osprey’s Hydraulics® LT 1.5L Lumbar Reservoir by Hydrapak is a hydration bladder made for those who prefer an off-the-shoulder hydration solution. Designed to fit in most lumbar packs, waist bags or bum bags, but perfectly pairs as an extra or replacement reservoir for Osprey's Seral lumbar mountain biking pack. Twin-welded chevron baffles stabilize the water and maintain a flat profile. Thoughtful design makes filling, cleaning, and—most importantly—staying hydrated on the trail easier than ever. All parts are BPA-free, phthalate-free, lead-free, guaranteed. All materials are certified food safe according to FDA and EU regulations.


  • Twin-welded chevron baffles stabilize the water and maintain a flat profile.
  • Easy Slide-Seal top opening, seals watertight and provides wide access for easy filling and cleaning
  • Magnet clip attaches to the reservoir hose and pairs with the included sternum strap magnet for easy water access and hose management
  • Hydrapak Blaster bite valve offers fast, smooth water flow with a ¼ twist on/off switch
