Unlike some traditional hydration bladders, the lightweight, innovative Osprey Hydraulics Reservoir has a HydroStatic backerplate that gives it structure and improves the fit of the reservoir in your pack.
A combination of supportive and pliable materials grants the Hydraulics Reservoir superior strength, and the durable TPU construction is both BPA and PVC-free. The reservoir’s wide mouth is easily accessed through a patented, leakproof sliding closure that further adds speed and efficiency to refills . An integrated PourShield makes the reservoir easy to fill and empty.
An anti-microbial treatment prevents mold and bacteria from building up inside the reservoir.
Available in 2-Liter and 3-Liter size options, the Osprey Hydraulics Reservoir includes a detachable drinking tube and a magnetic bite valve.
- Easy to handle when filling and loading into a pack

- Contoured HydroStatic backer plate preserves pack fit and comfort
- Magnetic bite valve attaches to sternum strap

Real Customer Reviews
- Great with Atmos 50 Xenith 105
Likes: Great addition to my backpack setup and 3L is great capacity for long hikes. However i am in PNW and we have lots of water resources around trails and never needed to fill it full. Also maintains its shape so doesnt interfere with the backpack capacity.
Dislikes: I have a Platypus bottle and sawyer filter and it is a little bit awkward to filter the water and fill the reservoir. Especially if you need to fill 3lt.
