Osprey Hydraulics Reservoir Review

The Osprey Hydraulics bladder is great for the hiker or backpacker seeking a bladder that retains its shape while filling it with water and exploring trails.

Performance Comparison

A look at the Osprey Hydraulics that fits nicely inside a hydration pack or backpacking pack. This 3-liter bladder is a perfect option for day hiking or backpacking for days.

Ease of Use

The Osprey Hydraulics hydration bladder offers an easy way to get your bladder in and out of a loaded backpack. A feature unique to the bladder is the ergonomic HydroStatic backplate that adds structure and rigidity to the bladder that maintains its flat profile when stuffed inside a pack.

The backplate on the Osprey Hydraulics makes this bladder durable and easy to slip into a backpack.

While this is a cool feature that many backpackers and hikers may enjoy, it limits the versatility of its fit. Since the backplate is rigid, it is designed only to fit inside of packs that are large enough to accommodate it. For example; if you have a 3-L bladder, you need a backpack that can hold a 3-L bladder. The bladder does not compress down, nor is it comfortable to wear with a running pack that requires a smaller bladder with a slimmer profile. That said, it provides a little more structure to an otherwise unstructured backpack, a cool idea!

We love the zip top that makes the filling and overall use pretty simple.

Another unique feature of this hydration bladder (similar to the Osprey Hydraulics LT) is that the hose doesn't connect at the base of the bladder, but halfway up the line, making it easy to unclip without having to dig through piles of stuff in your backpack.

The bite valve, up close with a bit of trail spice...

The bite valve features a twist-locking mechanism that prevents any unexpected water loss. We ran and climbed with it unlocked, though, and the bite valve doesn't leak. If you don't like the way the bite valve feels, or you prefer a different locking mechanism, the hose and bite valve can be switched out for pretty much any other option in this review.

The universal hookups allow you to switch out the hose. Shown here is a Deuter tube attached to the Hydraulics bladder.

Ease of Care

The flip-top design makes it easy to get inside and scrub the bladder reservoir if needed. It is dishwasher safe and can be loaded up on the top rack of a washing machine set to low temperatures. That said, because the hose connects halfway up the length of the hose, it's almost impossible to clean the section of hose between the base of the bladder and the connection point. A huge bummer. You also can't flip it inside out because of the backplate. Therefore, maintenance is key. Rinse and dry after each use. Make sure to blow all remaining water in the hose back into the reservoir and let it dry. To kill and suspected bacteria, put the hose and reservoir in the freezer until you're ready to use it again. Overall, this bladder is not the easiest to care for, but it's not hard either if you stay up on maintenance.

This disconnects at the center point. While this is great for on-trail purposes, we find the connector that goes from the bag is much harder to clean. The rest is simple. Simply open it up, rinse it out, or use a sponge to clean it without any problem.

Ease of Filling

The flip-top design features an extended spout and a handle that makes filling from a tap, river, lake, or trickling stream easy peasy.

We appreciate the handle that sort of help to fill up the Osprey Hydraulics system. However, it's a bit small, and when the bladder becomes more full, it doesn't work as well. Great idea, but it needs to be refined.

The rigid backplate keeps the shape of the bladder, even when empty, making it easy to pour and share water from this bladder. Overall, a super easy hydration system to fill up and share water.

Pinch it, and scoop up some water! We also appreciate the long tongue that offers great pouring capabilities.

Quality & Durability

This Osprey model is a high-quality product that offers a surprisingly durable design. The reinforced HydroStatic backplate protects from abrasion and friction while hiking. The outer film is a little thinner, so it's not as resistant to punctures as thicker options. The seams are welded and in good shape, while the quality of the plastics is bomber and well-crafted. There were no durability issues observed in our time testing this bladder, though some online reviews mention issues with punctures and leakage around the base of the bladder.

The plastic is a little thinner, which isn't as impervious to punctures. The connectors are high quality though.

Weight & Compressibility

Given the additional features and materials utilized in its design, this is a relatively heavy bladder. It maintains a slim profile when empty and can be left in the hydration bladder sleeve, but it cannot be rolled up or packed away to a smaller size because (a) the backplate is too rigid, and (b) there is no hose disconnect at the base of the bladder. As a result, its best for those who don't need to pack it away during their trips or adventures.

Here we see a few other bladders rolled up and compacted down. While we tried to do this, the Osprey Hydraulics is not rollable or compressible.

Value

This is an expensive bladder for the price. Many bladders that score higher cost less. Those that will find the value in this bladder will be looking for one with better structure and stability. We found this the easiest to stuff into a full backpack, for example, than any other bladder tested. If you need a bladder that can do that, this is a good price. Otherwise, look at lower-priced options that don't have this nifty feature.

Here we hike up Hayden Ridge (11,000 ft) with the Osprey Hydraulics bladder for easy hydration on the go.

Conclusion

The Osprey Hydraulics hydration bladder offers a durable and rigid design that makes stuffing it into packs and filling it up easy peasy. A solid choice for those seeking a great hiking and backpacking hydration bladder because it's so easy to fill from trickling streams.
