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.

Real Customer Reviews
- Great bladder
Likes: Fits well in my Osprey pack. I really like the backer plate which makes it very comfortable on my back.
- Designed for my Osprey pack
Likes: Light weight, easy to drink,
- Well thought out, effective...
Likes: It fits perfectly (it should) with the Osprey Aether AG 85 (backerplate keeps the shape nicely) and with the suspension system, I hardly feel the added weight of a full bladder. The bite tube works well and having a magnet on the sternum strap/hose keeps the tube from flopping around. It's not bad to refill and seems pretty durable. The top is well sealed, no leakage whatsoever.
Dislikes: Only reason for 4 stars is that is somewhat tough to dry out. There is a cleaning kit with a hanger, but it seems like at least the hanger ought to be included in the base price (probably the brushes too)!
- Big improvment over old model. Easy and no leaks!
Likes: After years of dealing with the screw cap this new fold and slid mechanism is a dream! Quick connect so I can refill without taking the tube out of the strap. The 2 liter fits perfectly in my Atmos 70 Pro and my smaller Daylite pack with ease.
Dislikes: The magnetic clip falls off /gets lost easy and has not changed since the last model. I use a small wrap of electrical tape to keep it on. Had to buy spares.
- More water tight than camelback half turn reservoir
Likes: doesn't leak, water is easy to fill, has the magnet
Dislikes: did not come w/ cover - it was back ordered, took a while to get it. And the cover pops off easily, which has more to do w/ the design of cap cover optional accessory than this product.
- Would Buy.
Likes: Very well made. Fits in pack perfectly. Easy to clean.
Dislikes: Takes a little time to refill when on the trail.
- Great Durable Design
Likes: Well designed for Osprey packs. I like the magnetic bite valve holder allows for easy access and you can readily position it wherever on the various pack straps on my Aether AG 70.
Dislikes: Took awhile to figure out how to completely dry it out after cleaning for storing in between trips. It is designed to stay closed which is great but makes it difficult to properly clean and dry.
- Overall great reservoir
Likes: Love the detachable drinking tube (making it no need to remove the whole tube). Also like the magnetic bite valve.
Dislikes: I also have the Gregory 3D Hydro Reservoir. Love the 3D form. If this Osprey reservoir had that same function, it would have been perfect. Makes it easier to hang dry.
- Works great
Likes: no issues at all.
- Ice cold
Dislikes: Heavier then lt
